PSU Overheating/Fan speed.

[vishwap]

Hi,

I recently changed my PSU fan and since then it started to overheat every time i play a game for more than an hour!
Was the new fan of a lower RPM? Should i buy a 2000RPM Fan?

Thanks,
Vishwa

What PSU do you have? The fan shouldnt need to be running full speed ever on a decent unit, im not sure if the fan on my EA500 ever turns on, i never hear it.

The RPM of the fan is important, but the design of the fan has a much larger effect. For a PSU since its such a small enclosed space you would need a fairly high CFM fan to maintain the pressure and force the air around the heatsinks.

What was the RPM / CFM rating of the original fan?
What is the RPM / CFM rating of the fan you're using now?
CFM = Cubic feet per minute of air moved by the fan. Also can be rated as cubic meters an hour m³/h

The CFM isnt exactly the best way to measure it, as 90% of companies over exaggerate by about 2:1 on the fans. Also, what size fan was it before, what PSU do you have, and what fan did you have before? You might want to buy a higher pressure fan, like made for dense heatsinks. This:

might make for a good PSU fan, although i wouldnt know.

Hi,

thanks for your replies.

My PSU is

I dont know the model number or anything about my new fan, but it is a cooler master fan and it cost me 250rs (5 USD)

The fan of my original PSU was replaced by this 5$ fan. Please tell me if it is ok, if not, then which is the proper fan that was supposed to replace original fan.

thanks all!

even if you cant get these from newegg, look for where you can. or you can just get the stock CM fan:

Your original fan was a Global Fan S1202512H: Global Fan website & fan specs

Try and match the performance of the original fan specifications. If you can find the model # of the new CM fan we can tell you something about it.
