hey, i recently installed a new http://www.overclockers.co.uk/showproduct.php?prodid=HS-035-AR

Artic Cooling Freezer 7 Pro.

So i got it all installed, but now the fan spins when the computer boots, comes up CPU Fan Error during post and it stops spinning? I have it plugged into the CPU fan header on the Motherboard, Wiped off the old Thermal Paste, Mounted CPU cooler screwed it in etc, I boot up and get as above a CPU Fan Error? Temps were idling around 29C but the moment i ran Prime 95 it shot to 50+ Degrees in seconds.

Currently using my brothers laptop as im scared to use my machine incase it fries :(


Please Help!

Thanks
Ross
 
if you are putting the stock cooler back on you should apply new thermal paste to it, and if you are sending the ac7 back then get something better as it really isn't a very good cooler with quad cpu's.

your temp of over 50c in prime with it is perfectly normal for a 3ghz + quad core.

Yes but not when the fan isnt spinning lol

What would you's suggest for around £15-20?
 
you have to take the motherboard out of the case and install a backplate, then the cooler screws onto the board. you can see the manual for it here - http://www.coolermaster.co.uk/upload/download/485/files/Hyper 212 Plus manual.pdf

if you aren't confident in removing the motherboard and installing the backplate then you will be stuck with clip on coolers :( in which case i would go with a coolermaster hyper tx3 over the ac7 anyday.

Im wondering if instead of going for something small like that now, if i just bear with stock and get a H70 eventually? Had a look on youtube and the TigerDirect/ComputerTV install dosn't look too hard.

It deals perfectly well with my i5 750 at 4GHz, and before that with my q8400 at 3.15. Not saying there isn't better available, but it's still a decent cooler.
 
when i had a phenom x2 550 unlocked to a B50 i had the ac7 at first and it couldn't keep it under 65c at stock speed (3.1), i got a tx3 to replace it and that was able to keep it just under 60c oc'd to 3.4ghz.

the ac7 is meant for dual cores or replacing a stock quad cooler with lower noise. it is only rated at 130w by the manufacturer and as soon as you unlock a phenom x2 it becomes a 125w phenom x4.
 
you could also try switching off the automatic fan control on your motherboard as well and see if it then runs ok at full speed.

the auto settings on my asus p5k premium are useless so i just run mine at full speed all the time.
 
I have the exact fan and did the same, its not a faulty fan its to do with the mobo which will have a very sensitive monitoring system. Best way to is to turn off the warning in the bios and check whether it is pwn controlled
 
The Smart Q Fan Funtion which i think is the PWM function on the Mobo? has always been enabled. And the AMD Stock cooler Speeds up and slows down as temperatures rise and fall, dosnt make any less noise when its slower mind you lol
