im going to be using a Intel Celeron 1.3 ghz socket 370 can you tell me what you thing is the best fanless heatsink?
hear is what I think im going to use, what do you think?
Zahlman stuff is high-quality. But consider a fan-solution anyways, some heatsinks are rated less than 25dB, below hearing
This does not look like a fanless heatsink in the way I think you want it to be. This looks like it was meant for rack-mount server cases where passive heatsinks are usually used on the processor and case fans are used for cooling the passive heatsink. This will not be a quiet setup- some cpu heatsinks are probably quieter. I would suggest doing the normal steps to silence a cpu and fan- add a resistor to the fan and underclock the cpu. For a Celeron this should work out fine- no reason to buy some $50 heatsink meant for server cases.Originally Posted by Sway
If you want a really quiet fan, yank one out of a Compaq workstation. Those are super quiet. I have a Compaq (old one WSpro A200 P3 500) . There is no fan on cpu HS but the case and the PSU fans are basically zero noise (well not really).
My Dell GX400 at work also has a very quiet fan.
The CD/DVD ROM generate more noise than the fan.
Why would you want a passive heatsink?
You have an internal combustion engine and you're worried about the amount of noise a 60mm electric fan motor makes? You'll never hear it over the engine or road noise.
Or are you worried about reliability? A processor with active cooling is less likely to fail then one with passive cooling. What happens in the summer months when your car is baking in the sun? do you really want passive cooling then? Processors aren't exactly cheap.
I really see no reason to use passive cooling.
Anyways I doubt you'll find a passive heatsink for a 1.3 Ghz chip. The last passive processor heatsink I saw was on a P-II 400mhz processor and it was gigantic.
In regards to the heatsink you selected, I use one of them in my desktop. It's not very good at cooling, but it is very quiet when the fan is as low as it can go. I would never use it in car though. Also, it requires that a fan is blowing on it to work. the only thing that changes is what the fan is attached to.

The threshold for human hearing with an undamaged ear is 0 dB, most CPU fans are 25-45 dB. My problem is that the quieter the heatsink the larger it is and I have limited space in my small caseOriginally Posted by jol

Looks very similar to the one your considering.
With the controller set to minimum at full load the temp has never gone above 45c.
The overhead fan assembly attaches to the pci brackets so it probably aint suitable for a carpc.
