Ok, I need help!

I am having overheating issues. I posted earlier about air flow and it helped, but when I crank up the load Im hitting 75c. This is my set up.

HP case with the following.
90mm exhaust on lower back.
80mm exhaust on side
120mm intake on side.

Could it be that I put my thermal paste on too thick? Or is it still air flow?

Stock cooler?

Its about 70° f in the room, on the ground with room around the box, very clean, brand new CPU just installed with stock heat sink. Dont know about the side fan.

You could spend like £10 (17USD) and get a nice cooler - problems solved without too much faff around. Though, you could also try changing the fan setup so both side fans are intakes or something like that.. see if that helps.

I have an ASUS M4A785-M motherboard, how can I find out the socket type I have to make sure my new heat sink is compatible, and what are some good cheap heat sinks?

Your motherboard will take any AM2, AM2+ or AM3 CPU cooler. This means you have a pretty sexy collection you get to pick from. In the UK there's ebuyer.com which have amazing selection for AM2/3 socket, for the US i believe a lot of people go to newegg.

A few coolers that you do you well (best + most costly first):

Zalman CNPS7000C-CU

Arctic Cooling Freezer 7

CoolerMaster Hyper TX3

I've got the Freezer 7 in my old machine and it's cooling a AMD dual core at 3.01GHz just fine, running about 35C at idle, 45C under load.

Just double check they can actually fit into your case! HP cases are often thinner than a standard ATX case.

Update! Hey all thank you for your help. I went out today to the local computer place and the guy there had a left over 6 core heat sink that had a copper base and heat pipes. Bought it for $20 and it dropped my core temp from 72 @ load down to 34 @ load! Im golden now.

That's great! I sold my 6-core stock cooler with an older CPU because they are pretty good for anything less than a 6-core. Very nice temp drop!
