New build overheating.

[Randygiles]

This is what I've got and assembled.

Item: Corsair CWCH50-1 Cooling Hydro Series H50 High-performance CPU Cooler supports LGA1156 LGA775 LGA1366 AM2 and AM3 processors - Qty: 1

One problem is that it won't recognise this HDD which I transferred from my old comp (the one I'm using now) but I have a spare HDD which I'm going to try and format and put windows xp on for now when I can find the disc.

But the main problem is that when I went into the bios it said my CPU temp is 88c. To me it seems the fan is working fine but according to the data, it isn't.

Can anyone help?

For some reason it doesn't want to paragraph :S.

If you want me to take a shot at editing your original post with paragraphing, I'd be happy to do that.

Your overheating (assuming it's really overheating) is likely caused by a CPU heatsink that's got a loose pin. Try wiggling the heatsink. If it moves at all, then one or more of the four pins is loose.

I guess it's also possible you have missed applying heatsink compound on the heatsink/CPU interface or you've applied WAY too much compound. You only need a thin layer of compound. Instructions often call for the total volume of a few grains of rice.

What you'll see in the BIOS with a loose heatsink is a quick temperature rise (from room temperature) when you first turn on the computer.

Yes please, also the heatsink was properly fitted but also came with a lot of thermal paste on it. I've tried to clear some off and left only a small amount in the middle and tightened up the pins as well. I'll see what the BIOS says now...

 

[Randygiles]

The temperatures start off at around 45c and slowly rise until around the 60/70s where they begin to rise faster :S. I'm going to try the stock fan atm and see what the temps are.

 

[Randygiles]

Ok I've put the stock fan in but now it just endlessly reboots . There are 4 phase lights on the motherboard, 1 and 2 are green 3 is orange and 4 is red.

 

[Randygiles]

Ok forget all that, with the stock fan the temps are hovering at 36c. Should I get a refund on the corsair h50 or try again with it to see what the temperatures do?

Try again. Also the heatsink should be hot to the touch. If it's not hot than HS to CPU contact is bad. Try refitting it
