Stock CPU fan issues

I recently built my second system. I have Intel Core 2 Quad Q9550 Quad Core Processor LGA775 installed and ready to go. However, when i first booted up, it gave me a "CPU fan error!". I did check to make sure it was connected to the CPU socket on the mobo. I went into bios and noticed the CPU temp. It started around 44 and slowly climbed until it reached about 70c. I read on some forums that i should change the fan settings and disable Q Fan ect, which I did. I no longer get the error but the temp still goes up like before. I guess all im wondering is how can the stock HSF that came with my CPU be that bad? Is it maybe defective? Im sure it would go higher than 70c if i let it. I think what I will have to do is purchase a new HSF.

Anyway just wanted to know if thats unusual or if maybe theres something im missing.
Thanks!

Most likely you did not seat the heatsink correctly. The push pin mounting can be a real pain as well and it is best to mount any heatsink while your motherboard is outside of the case so that you can make sure the pins are through the holes on the underside of the motherboard.

you will also need to buy new thermal paste and I assume you have just used the stock stuff that came with the heatsink. Just make sure you clean off the old stuff with a microfiber cloth and some 70% or higher isopropyl alcohol on both heatsink and cpu.

here's a vid on how to remove, install, clean and add thermal paste to a cpu.

good luck hope it helps

I have the P5Q Pro mobo and had problems with the idiotic push pin mounting system (Intell are you listening ??) and eventually bought a HSF with a bolt on back plate.
