How do I change the fan
hI my fan is very loud at times, it vibrates a lot. It make the sound of a lawn mower. I took it of and i found a lot of dirt , i have cleaned it pretty well, i also saw that the thermal paste on my cpu and video card was completly dried up. The thing is, after cleaning the fan, she still make that awfull sound. So i think i need to replace it, but i dont uunderstand how to take it of because she is attached to the copper bar that goes on the cpu . excuse my english im french, can someone help me, how would that cost if i make it change by a professionnal ? thank you
