| 477714 | 2006-08-11 00:51:00 | Hi guys, my old faithful system has developed a wee noise at cold boot, doesn't last long, but is getting worse. I have pinpointed it (hopefully) to what i believe is the cpu fan. I have ordered a new one which will be here next week. I opened it up and gave it a good clean, heaps of dust! However it doesn't appear to have helped, obviously the damage has been done, and the guys i talked to at the shop said that this is common, dust getting into bearings... The fan is actually still working, but i guess it won't be long till it stops altogether now. Basically i just wanted to ask if anybody has any tips for me when i replace it, as i haven't actually ever had to work with a cpu as such (replacing or installing). I know the important thing here will be the heatsink, anything else anybody can advise would be appreciated thanks :). Or will it be pretty straight forward i guess. CPU: AMD Athlon XP 1600+. Also is it o.k to keep using it till i get the new fan installed? (system is still working fine). One tech, when i ordered part, said yes, that when its not making the noise will be the problem (as i presume that will be when the fan actually dies). I really don't want to trash/overheat the cpu, but the fan does appear to be working fine still. Cheers |

I will be rapt if i don't have to remove the heatsink, as i would prefer not to have, i had initially thought i may not need to, but the tech had said that it came with the fan etc and to do it. So going from memory when i was checking it out last night, it just screws on then? would that be right? Cheers |

| 477717 | 2006-08-15 02:36:00 | Hi again, just had a great laugh to myself :). My new fan just arrived and i am about to install it. As i had said earlier, i have never had to work with cpus as such, so when people had been saying i wont have to touch the heatsink, it gave me the impression the part i would be buying would be the "actual", top part of the fan - i.e the fan, that sits on top, lol. I just presumed from the price of it that was all i would be getting... feel a bit silly... :blush: Anyway, now i can see i got the "whole fan" :blush: , the guy at the shop said i should definately replace the heatsink, also gave me alot of nice tips as well :) , i guess i will see what it looks like when i get to it. I can imagine after 5 odd years it (heatsink) may be pretty bad? |

| 477719 | 2006-08-15 04:08:00 | Be gentle when removing the old unit and be careful with the thermal paste or tape... any doubts ask first! | Greg (193) | ||
| 477720 | 2006-08-15 06:09:00 | Thanks for the link Developer, i had just downloaded it and was preparing to make a start and my power went out... hope thats not a sign of things to come. So now the powers back on, i've decided to make a start on it after dinner and see how i get on. I hope it will go fine, the shop tech was excellent at going through it with me, (they always are), explained how best to get the old paste off, clean it etc... Greg, yes, i intend to be veeeery very gentle :) Thanks |

| 477721 | 2006-08-15 09:48:00 | Well i have got the old heatsink/fan off now and am about to clean off the old paste, well actually it appears to have been a pad or tape. I just wanted to check one thing - with regard to the compound, the link Developer gave me said to apply it to the actual heatsink, whereas i was told to put it on the cpu or both, searching gives varied results also, and the instructions dont even mention the compound at all - which is correct please?:). Also the pad covered an area right "around/outside" the chip? by about 5 to 8 mm, should i use that as a guide or is that too much? Thanks guys appreciate your help :) |

| 477722 | 2006-08-15 10:00:00 | Apply the paste to the CPU, put depending on what chip you have there are different methods. If the die is exposed like on P3's and sktA Athlons then you'll need to spread it evenly over the core(use a bussiness card or something similar). But if the chip has a heatspreader like all P4's and Athlon64's then just put a small blob in the center. In both cases dont use any more thermal paste than about half a grain of rice. You can apply thermal paste to the HSF, but its normally only to smooth the surface. Apply a small ammount and then rub it off gently, in theory the paste fills in any small scratches in the surface and improves heat conductivity. | Pete O'Neil (6584) | ||

Thanks Pete, that sounds like exactly what i thought i ought to do, cover the core, however i wasn't going to put it on the heatsink as i just read "do not put it on the heatsink" Here ( . com/digest/Howto/cpu/socka/4 . html" target="_blank">duxcw . com) So your advice is a tiny bit to the HSink, thanks:), i will go with that then, lol, i will be here all night umming and arrhing about it otherwise . Thanks most appreciated . |
