Hello tom's hardware forums. I was hoping to get a little advice on what to do about my current heatsink/fan and cpu. My current heatsink and fan are horribly clogged with dust from owning the pc for quite a few years and now my current temps under heavy load (running borderlands 2 at max) ranges from 61-70c I know these temps are horrible. I have hit my pc with a good few cans of compressed air but as I have seen no improvement in temps in the past few weeks im sure that I need to replace my cruddy stock heatsink/fan clean and re-apply thermal paste to the cpu but im terrified of trying. I have never tried to remove hardware from my pc and am quite new to hardware replacement and extensive cleaning so I was hoping somone could find the time to give me a clear set of instructions for my specific mobo and cpu. also suggestions on what heatsink fan and cooler to buy for my pc next month im going to have a good amount to use on this problem so its not really a tight budget around 100-200$ to spend on it. ok so lets get down to hardware :)  My current rig is a modified version of this (http://h10025.www1.hp.com/ewfrf/wc/document?docname=c02...) the changes I have made to this pc so far is replacing the stock psu with a Silverstone strider plus ST50F-P 500W ATX 12V v2.3 & eps 12V 80 plus bronze certified psu and putting a Nvidia GeForce GTX 650 Ti boost in.

"...im sure that I need to replace my cruddy stock heatsink/fan clean and re-apply thermal paste to the cpu but im terrified of trying."

It's not that hard but it does take a little experience to know what to look for and how to do it. You can find videos on each topic but if you're still don't feel up to it just take it to a shop and ask them to clean everything and redo the heatsink with new thermal paste. Maybe just add a new/better fan. If it ran this long without an updated heat sink there is probably no reason to replace it. I'm not sure how proprietary the HP build is but it may not be a straight forward process to update the heat sink/fan.

what do you mean theres no reason to replace it 71c is max temp this cpu can go and im hitting 70c if I don't do somthing my cpu is toast :( . I was just looking for someone to give me advice on parts and explain how to do it myself because I want to learn how to do this. if anyone knows a guide on replacing the heatsink/fan for my am2+ socket please link it to me and also what thermal paste I should use and what method to apply it with. It should be a straight forward process my pc is a few years old but its not anything unusual.
oh and recently my pc has been crashing going into sleep mode.I turned it off because I read that win7 has issues with sleep mode can anyone confirm this?
