But there is a little, but have to ignore it, what else to do?? :lol:

Maybe since you CPU is a 920 instead of a 820, the fan spins slower. I couldn't tolerate the noise of a 820 based system :eek:

Oh ok. But I just told you to add one in front of the hdds rather than underneath them. I didn't say it was compulsory to have fans for hdds, right?

[zCexVe]

I got 8 fans..

1-CPU fan
1-VGA fan 3000rpm
1-Heat pipe kit+north bridge 3000rpm
1-south bridge-3000 rpm
2-PSU fans 5000 rpm

yes but see the manual 1st.
Some manufacturers have their SYS_FAN conn: the sensor.Some have on PWR_FAN.thats rare,but there r some.

[Anusha]

The power cable????

Not those fans with molex connectors. There are fans which has both the molex connector and the three pin motherboard power connector. You have to use those fans to read the RPM. But they usually spi at 2000-2500 RPM at the default 12V (0.1A)

Wow! You sure those two PSU fans spin at 5000RPM? With all those fans, you must be like sitting next to a jet engine!

yep,they r transparent,got 4 blue LEDs each and spin @ 5000MAX and can be controllable.Thats why i payed 5500rs 4 the PSU...I usually run them lower than half of speed..If not there will be some sound...

[Anusha]

I also paid Rs.5,250 for mine, but this was more than 2 years ago. Mine doesn't have those fancy stuff, but does a very good job with the power. The only thing I miss in it is the 24-pin ATX connector (but most motherboards are still backwards compatible with 20-pin one)

[shanX]

Oh ok. But I just told you to add one in front of the hdds rather than underneath them. I didn't say it was compulsory to have fans for hdds, right?
Yep I know it isnt compulsory and btw i told u am gonna have em infront of hdd's. And I'll take off the only useless item I brought, fdd. And there is a slot for a 2nd fdd, I'lll remove its cover and I'll have some grill or net over em and use it as air vent ;)

I got 8 fans..

Noise is a big problem! Maybe not to you. But I and some people here leave the PC on throughout the night. It disturbs us to have sweet dreams. Besides, if your CPU is stable, then don't worry much about the cooling. You are not gonna use the same CPU for more than 10 years no?

Maybe, fan controllers would be better. Turning them down is better than turning them off. Besides, you might hit a sweet spot where it doesn't let the system get much hot, and not irritating the ears at the same time.

[shanX]

But there are some not much useful fans....

[Anusha]

Such as?

[zCexVe]

If they rnt useful why would u keep them..
Anushas saying is right.I have tuned my PSU fans to a sweet spot-no much heat nor noise..
there r fans with speed controllers ucan buy them,controller fits in at pci card window of casing.
U can build them for about 40~50 rs.needs just two wires and a variable resistor like in radios..
Pasan will be very kind to help us out,wont you???

[Anusha]

You can also use two way switches to make the fans work at either 12V (default) or 7V. You can give the yellow wire from the molex connector permanently to the positive terminal and either the red wire (5V) or a black wire (ground) using a two way switch to the negative terminal to make them work at 7V and 12V respestively. You can use the 12V supply when doing heavy tasks and 7V supply when not doing much work.

This way, you are not wasting power either. If you use a resister, then even when you turn down the RPM, it will still dissipate the same amount of power as at max RPM. I know, it's a small power, but we should try to cut power as much as we can, if we can. Think of how much electricity we will be saving when we add them all up from everyones's PCs.

You don't have to cut them. You can carefully get them out of the molex connector using a hard pin (you have to bend the two small notches that's prevtning them from loosening), and interchange the 0V and 5V (red) and you'll get 7V (12V - 5V).

I dont get how we get 7V frm interchanging 5v & 0v.I only knw to get by interchanging +12V yellow and -5V black with red one..

I need the circuit , parts and estimated cost buddy;);)
where can we find heat sensors:confused:
I got messed up while fitting my CPU heat sensor.I fitted it between CPU and CPU Cooler,sothat when i fitted it coz of the pressure the heat sensor was flatted:([the tiny little resistor]
I got a CPU heat sensor frm PIII mobo and fitted it :cool:.
Its sensing is gr8 than the previous one:yes:
But i'd like to buy them if i'm making a circuit..

There are no negative voltages coming out of any connector :confused: They only go into the motherboard through that big ATX power cable. The normal molex connector has 12V, 0V, 0V, 5V. Besides, +12V and -5V will give you 17V!!! :P

More fan's is not always good. It can sometimes make things hotter!!! You might not believe it, but it can happen. You shouldn't let the air pressure build inside the case. It has to flow smoothly. The best configuration is, bringing the air into the case from the inlets in the lower front, and throw it out from outlets in the upper back (near the CPU). ATX standard is designed like that. AT motherboards had the CPU in the front, lower section, and this wasn't efficient when the CPUs become hotter and hotter. So they rearranged the ATX component placement.

It's even better if you have a duct in front of the CPU to bring the cool air in with the vacuum effect of the CPU fan, and a power supply unit which will take in the hot air around the CPU into itself and throwing outside from the back (i.e. two fans).

[Anusha]

Which make and brand? I yesterday spotted in an article than Maxtor DiamondMax 10 dissipates very low power compared to all the other HDDs from other manufacturers. It was like 10W vs. 19W. Mine is a Maxtor DiamondMax 10 320GB, and I have to say, it's cooler than my 160GB Samsung! Samsung and Seagate generally make the coolest and quietest drives.

oh u knw what they teach for GIT in O\Ls..
this is the 15th MCQ of there paper frm ma school
15th
How much data can a cd hold up?
I asked what CD(22 mins or 80 mins)no answer..
35th
How much data can a cd hold up as a multiplier of Floppys'data
7(00/1.44=486)

34th
What is the maximum FSB in a mobo now?
correct ans was 800Mhz..
fortunately i got the paper b4 print and corrected it to Intel and 1066Mhz.Then the Q was removed coz teachers dont knw about that..
19th
In what gazzette that says about pirating CDs/Softwares illegal?
ans is 14th of 1995 I think..

Remember all these r in Sinhala..

[zCexVe]

there r more funny things like that..I dont hav the paper with me right now.If then we would laugh for a month..If i can i'll post the paper i made for taking members into ma club..[I'm the secretary thats why]

http://www.uoguelph.ca/~antoon/circ/auto-fan.gif

This is the actual size of the circuit
http://www.uoguelph.ca/~antoon/circ/autofanl.gif



"This circuit was designed to automatically activate a set of three or four small DC fans to cool a large cool-rib for a 10 Amp powersupply. Can be used in a variety of other applications as well."

Couple Notes:
Th1, the 50K thermistor, is a standard type. Mine was a bar or rectangular looking thingy. Available from Tandy/Radio-Shack. Almost any type will do. I experimented with different models from 22K to 100K and all worked fine after replacing the trimmer pot.
The one used in the above circuit diagram was a 50K model made by Fenwal (#197-503LAG-A01). This 50K was measured at exactly 25 °C and with 10% tolerance. The resistance increases as the surrounding temperature decreases. Tolerance for my application (cooling a large powersupply coolrib) is 10%. Another name for this thing is 'NTC'. NTC stands for "Negative Temperature Coefficient" which means when the surrounding temperature decreases the resistance of this thermistor will increase. You may have to shop around to get the cheapest price. Some thermistors can be had for as little as $4.00 but as much as $55.00 Canadian currency for the glass encapsulated type (the best).
I replaced my thermistor for a 60K hermetically sealed glass type since the environment for my application may contain corrosive particles which may affect performance on a future date.

P1 is a regular Bourns trimmer potentiometer and adjusts a wide range of temperatures for this circuit. I used the 10-turn type for a bit finer adjustment but the regular type may work for your application.

R1 is a 'security' resistor just in case the trimmer pot P1 is adjusted all the way to '0' ohms. At which time the thermistor would get the full 12 volt and it will get so hot that it puts blisters on your fingers... :-)
R3 feeds a bit of hysteresis back into the op-amp to eliminate relay 'chatter' when the temperature of the thermistor reaches its threshold point. Depending on your application and the type you use for Q1 and Re1, start with 330K or so and adjust its value downwards until your satisfied. The value of 150K shown in the diagram worked for me. Decreasing the value of R2 means more hysteresis, just don't use more then necessary. Or temporarily use a trimmer pot and read off the value. 120K worked for me.

Transistor Q1 can be a 2N2222(A), 2N3904, NTE123A, ECG123A, etc. Not critical at all. It acts only as a switch for the relay so almost any type will work, as long as it can provide the current needed to activate the relay's coil.

D1, the 1N4148, acts as a spark arrestor when the contacts of the relay open and eliminates false triggering. For my application the 1N4148 was good enough since the tiny relay I used was only 1 amp. However, you can use a large variety of diodes here, my next choice would be a regular purpose 1N4001 or something and should be used if your relay type can handle more then 1 amp.

If you like to make your own pcb, try the one below. The pcb is fitted with holes for the relay but may not fit your particular relay. It was designed for a Aromat HB1-DC12V type. The variety and model of relays is just to great. How to mount it then? Well, I left ample space on the pcb to mount your relay. You can even mount it up-side-down and connect the wires individually. Use Silicon glue, cyanoacrylate ester (crazy glue), or double-sided tape to hold the relay in place. Works well. Note that the pcb and layout is not according to the circuit diagram in regards to the hookup of the fans. The PCB measures approximately 1.5 x 3 inches (4.8 x 7.6mm)
If you print the pcb to an inkjet printer it is probably not to scale. Try to fit a 8-pin ic socket on the printed copy to make sure it fits before making the pcb...

Hey friends this Anusha's CCT is working more than perfectly. Fans r vary its speeds like processor fan. And that circut is vary very smoothly.

U dont want any electronic knowledge to make this cct.

I use these parts to make this cct.

1) IRFZ44N ( Normally we cald FET. And that last N means N channel )
2) 3.3k thermister with 2.2K resister ( Couz 10K thermister eka hoyaganna bariuna nisa )
3) 10K preset

TRY IT. And Reduce ur fans noise:yes: :yes: :D :D :D

I'll upload some pics latter:yes: :yes: :yes: :yes: :yes: :yes:

Then dont bite it's pips your self...

[Anusha]

:P :P :P
Anyways, the only advantages a water cooling system has over a good air cooler is the noiselessness.

[chaminga_d]

stupid person....

[chaminga_d]

Nobody has ever doubted the advantages of water cooling as compared to air. Water is some twenty five times more efficient than air at conducting heat, which makes it an obvious choice for cooling all manner of hot running computer components.

[chaminga_d]

Unfortunately it also comes with several disadvantages too.

Yes machan. PC walata witharak nemei Watter cooling set karanne. Samahara Hi Power Out thiyena transmitters walatath watter cooling danawa. They use Special liquid. Mama ehema ekak dakala thiyenawa swarna wahinee eke athuledi

[zCexVe]

Too for about 3000W amplifiers like things..
BTW there was a guy in SL who produced a cheap and gr8 watercooling system which costed around 2500Rs. at that time in 2005 who won a runnerup or winner in a foreign competition for new inventions told that he will produce it to market with some alliance with a company in a 6~12 months time but I never heard of him after that which is very unlucky of us coz if it has been active,we would never run hot.
Sorry 4 the very long sentence.I'm used to them.

Pasan did u fix the resistor with the thermistor?does thermistors have N/P poles?
what about that tiny heat sensors comes with Mobos located in the middle of some processor sockets? (formerly ZIP sockets?)

[Anusha]

I think there are both unipolar and bipolar thermisters. Haven't used them in any circuit, so I have no idea at the moment. But looking at the circuit diagram, it looks as if they are unipolar ones as the cheaper ones are resisters which chance their resistive properties according to temperature.

Dunno anything about how those motherboard heatsensors work.

BTW, that's ZIF (Zero Insertion Force) socket, not ZIP (if it wasn't a typographical error).

[zCexVe]

sorry buddy i was in a hurry.helping mom,typing posts ,helping dad etc etc...
I'll correct that,and now i realized that not all zif sockets have a hole in the middle[Like socket 939]..

No man. Thermister is also a kind of RESISTOR:yes:

[zCexVe]

no no.. the 100 ohm one..Is it a thermister too?

[zCexVe]

Then pls post ur circuit diagram...I'm confused now..

[Anusha]

Aren't we talking about the one given in the 144th post?

Oops!
You've got wrong.
I meant not M/B.
I had IBM Mother Board. when it was working I had one fan...
It's only PSU Fan.
But I lost that M/Board because of some Circuit problems.
Now I have GigaByte M/Board with same Hardwares.
But the new M/Board doesn't fit 100% for my Casing.
So I put a new Fan...
then Now I have got 2 Fans...

[Anusha]

What do you mean by, But the new M/Board doesn't fit 100% for my Casing? And what's connection between that and the fan?

[zCexVe]

IBM casings r made for their mobos so its very hard to put another one ,actually a common vendors' one ,in it.U can see the trouble by buying a HP casing that r everywhere in gov offices and schools.Ur ATX PSU wont fit in there.U hav to cut the casing..
And if u use a IBM PI or PII u r right.Some of them had PSU fan frm the Mobo it self with heat monitoring..Kindda weird.Nowadays it is done by the PSU it self.At least mine.

Now dont think I had one.@ ma frnds shop he repairs all kinds of PCs.So second-hand imported DELL,IBM,HP,Micron u name it evrything comes there.
I saw two of this kind which came about 7-8 months ago.It had 3 fan jacks all with sensors.PSU,CPU,Casing.
There was another IBM or DELL one with a weird rectangle blackish brown thing connected to the power button in one PC.It was a P2..Two wires connected.corners r round.We never figured out what it do.
Anybody know of this thing?
