I5-2400 stock fan issue

Last response: in CPUs
April 9, 2011 5:19:54 AM


Just updated my socket 939 system to a lga 1155 setup. I used the i5-2400, asus p8p67-LE and 4 (2x2) kingston hyperx blu

I kept everything except the mobo, ram, and cpu the same and prior to the upgrade my PC was silent.
Now all I can hear is the aggravating whining sound of the lga 1155 stock cooler.

I put together a i3-2100 for a friend a few weeks ago and his system was must quieter than mine. Before my upgrade my system was inaudible (scythe fans, antec p180 case, arctic cooler freezer 64 on the 939 socket cpu).

I really hate the noise, but if it's normal and other users are experiencing it I wont feel like I got screwed.

Should I ask Intel for a replacement stock fan or buy a aftermarket cooler?
I don't know if the i3-2100 receives a lower RPM pwm fan or the same as the one I received with my i5-2400?

Check the fan is seated properly.

The fan on my i3-2100 is a complete joke, not sure what the stock i5 fan is like.

You can lower your fan speed as long as the temps are ok.

How do you check if it is seated properly?

One weird thing. When I took the fan out of the processor box - the plug in was stuck under the fan blades.

I had to wiggle it out from under the fan blades as it was stuck under and in between. It had to be like this since packaging at INTEL. I was careful when taking it out and didn't use any forceful motion, but I wonder if that didn't cause any issue with the fan.

Again how do I check if the fan is seated properly?

Or are you meaning the heatsink?

Lowering the fan speed makes the whining more prevalent. Having Q-Fan enabled with the fan set to standard I hear whining. Having Q-Fan disabled or enabled and set to "manual" the whooshing of the fan at 2000 rpms somewhat covers the whining. I don't want whooshing or whining.

Maybe my friend got lucky with his i3-2100 being silent? I got him a rosewill blackbone case to go along and antec psu - it's all inaudible.

Yes, I meant the heatsink. My i5 2500K is pretty quiet.

what if I just got a bad stock heatsink fan? is it possible to get a bad brand new fan?

I'm getting mid 50 celsius temps under load and low to mid 30 celsius idle... does that seem normal? What do you get with your stock HSF on 2500k?

Just installed ASUS AI Suite II's EPU -- to monitor temps instead of "CORETEMP".

Core temp showed the mid 50's load and low to mid 30's idle.

EPU shows temp of mid to high 20's idle.

gonna go see the temp under load.

what software is best for temp monitoring?

RealTemp and HWMonitor are good.

What are you using to load it with? With LinX, I get ~70 degrees C junction temperature. Check those temps aren't case temps, but I doubt they are.

Well, mid 50's is fine, and seems about right for that kind of load.

Check there are no wires or anything touching the fan, and that it isn't out of shape (including from dust!), cracked or anything else (especially check near the blade tips).
