Overclocked to 4.0 with 20x Multiplier and 1.325v i believe if i remember correctly.

Testing with OCCT to try and hit below 62c on full run for hours ... system always stops at 63 for automated shutdown just to re-tune.


I am having trouble keeping this system below 62c with 5 fans in my case all great flowing... and two Corsair HP SP 120mm fans mounted to the hyper212 evo with non-pwm setup...



How the hell do I go about raising the two cpu/chasis fans connected to the heatsink... I've tried BIOS, speedfan, fan Xpert, to no success.


I am stumped do i need the PMW fans to control the speed..... and also... sec let me boot up and let you know about a weird question also....


Couldn't find exact numbers but one fan in bios keeps bumping up to like 68000 rpms... it doesnt run over like 1100-1200rpms but keeps fluctuating between those numbers. (Real numbers and the crazy one.)


I believe these to be rated at ... 2500rpm? yet they only run on 1100-1200 max at all times. Can't seem to find a way to get them to run any higher to stabalize crazy OC's.


and sry .... Asus M5A99fx Pro r2.0 MOBO

There should be a setting in the BIOS for fan level control and target temps. It wont be in the section where you overclock but around the Chipset configuration or somewhere like that.

Also, those are the quiet model of fans from Corsair and wont spin as fast. You would probably be better off running the stock Hyper fans as theyre actually very good.

Go into the BIOS and see what the voltage is set to for the CPU/NB. If its set to AUTO, set it to manual and set it to 1.15V if youre not overclocking your CPU/NB (and you really shouldnt be because it adds virtually nothing to performance). This will shave off some heat for you.

You can always plug those fans into your power supplie's molex connector if you have an adapter. That...

So .. I am confused completely.

Shouldn't hooking up fans directly to the fan header run at 100% full speed all the time... I see 1100-1200 RPMS on all fans ... and my ordered fans were rated for 2500rpms i thought ... sec I'll link.

I bought these running two front 140mm (stock cam with rig) and three of these corsair fans ... but they are only reading around 1100-1200 rpms on headers ..... I am confused.

ANY HELP!>!>!>!?!?!?! IM GOING MAD!!!!! lol

thanks in advance..


I guess I'll look to see if headers split volts somehow??? they shouldn't tho......

and check Qfan and things, but I am sure thats not it.
