I have a few questions about making my T-bird a little quieter. I saw this site in PC World and I read some of the articles. I definetly want to make my computer quieter, it's driving me crazy!
I tried the quick and dirty 12V to 5V fan mod (didn't put the switch in though, just some good old wire splicing), and boy did it make a difference. The only problem was, my CPU was running much hotter (temp viewed in either the system BIOS or Motherboard Monitor 5). The rise in temperature wasn't unexpected.. the fan was spinning twice as slow (2500 RPM vs 5000 RPM).
I did a quick Google search to try and find out what the max temperature was for a T-bird but I didn't find much. Does anyone here have some figures? It was getting up around 145 F, which I OK with because it didn't seem too hot for a 1GHz chip. The weird thing was, during the night (yikes) it spiked to 175 F!! I have to say that I run the distributed.net client all the time, so that is obviously going to make the CPU much hotter than the idle temperature because of the constant data crunching.
I spliced my fan back into a 12V screamer because I wasn't comfortable with that spike. One thing I noticed when my fan was running at 5V was how loud my hard drive was! It was always drowned out in the noise of the fan but I could really hear the whining (I'm pretty sure it's a 7200 RPM).
Okay, here's my questions:
What is the max operating temp of a 1GHz T-bird?
What is a good choice for a quiet fan, or a heatsink good enough to run without a fan?
I want to make my power supply fan quieter too, but it doesn't have a built-in thermistor like the CPU does... how can I get it quieter without letting it overheat?
