How can I control CPU fan speed?

Here's the issue, I have ASUS mobo with the suite, the reading for COU is 102- degrees off, ie useless, core temp reports 75 deg under prime, my dumbass suite tells me it's 55 degrees (I have of course used mutiple of these progs at once to make sure)

The useless thing and bios is not allowing me to go back to stock either, only a mild OC of 3.6ghz tho.

Therefore the cpu fan does not speed up and my cpu hits 83 degrees (shutoff point i set with coretemp)

This means any activity (even the map on MTW 2 causes a shut down) - I can play SKYRIM for about 2 mins, causes shutdown.

I really need something that accurately records CPU temp and and controls the CPU fan and ideally the case fans.

Please no lecture on only having a stock cooler right now, I am without a TV and need to save for one.

PS - I did take off cooler clean off and re-apply paste (pea size grain spread thinly, the cooler is set solid too).


Thanks.

Thanks.
 
With Speedfan you can adjust the fan curve so that it ramps up at any speed you choose and also offset any recorded temperature so that it's close to the true temperature. For example on my i7 Speedfan reports temps 11 degrees higher than real temp reading so I just adjusted accordingly. Once you've done that you can fiddle with PWM reaction.

Thanks, what is PWM reaction?

What fan curve?

edit: Tried SF, it does nothing. Fan speed still tops out around 1500 as CPU temp careers over the edge.

Not sure if it's the right terminology but basically it's the amount of On time versus Off time that your fan gets as a relation to temperature. It's expressed as a percentage of on time, starting at say 20% and rising to 100%.

What fan curve?

Every automated fan control will have some form of graphed curve which governs how fast the fan goes in relation to a given temperature. The graph may be editable or not editable. In the case of motherboard CPU headers it's quite often a BIOS configureable setting where you input the amount of PWM per degree above a certain level.
 
Sorry you've lost me.


This is nuts I hit 'full speed' on the asus fan expert, it sounds like a jet taking over the cooler goers over 2000rpm and STILL it will not stay under 80, nothing stops the temp rising.

I would consider a proper cooler, but clearly the rising temp is not causing the fans to kick in as they should, why would they with a proper cooler?

Another day completely wasted.
 
its the cooler mounted properly? also is it the stock cooler? its terrible.

buy a proper cooler :)


I think so, it is rock solid, all pins pushed thru, I applied a thin layer of AC MX-2 (had to go purple :() spread evenly.

Yes, I know about buying a proper cooler as I said the opening post, I also needa TV. My concern is should I buy a cooler, the problem continues and i'm down £50.

In your opinion should a stock cooler at 100% be able to stop a CPU overheating with prime blend in operation?
 
Sounds like the stock cooler isnt seated proper, they can be a pain and look like they are seated but arnt.
How hot to the touch is it.
