First post. Brief introduction is in order. I'm an electrical engineer from MN. Computer is an Athlon 1.4GHz, ECS K7S5A, Radeon VE, and the usual, standard stuff.
This all started when my sister got a brand new Dell, which was ultra quiet compared to my computer. All of a sudden, the same old fan noise became intolerable. So, mimicking the Dell design, I took out the CPU fan on the heatsink and ducted the air flow to the fan on the rear of the case using a crude duct made out of cardboard box (from a X-mas gift box). This helped, especially when the fan was mounted to blow out.
Adding a 10ohm resistor to the fan helped further, albeit a 5C increase in CPU temperature, which now peaks at 64C with case temperature at 30C. Panaflos will be next, when I order parts from newegg next time.
I also want to switch to a copper heat sink, but I'm concerned whether I can simply swap out the heatsink. It's got the stock AMD heatsink/fan that contacts the CPU by some sort of double-stick tape. At the very least, I want to replace that double-stick tape with some Arctic Silver. AMD engineer once told me that removing the heatsink after it's been fused is not good. I'm not sure I quite buy that. I can't see how it can't be scraped off with a razor. At the same time, obviously, this is a one way street: if it won't go back on, I need a new processor.
So, does anyone have experience with removing/replacing a heatsink that's been fused to the CPU by this "double-stick tape?" BTW, where would be a good place to buy fans, heatsinks, and such? Newegg shipping kills.
Thank you for you help. It's good to be here.
