Passive Cooling

Valo · 15 Aug 2006 at 11:39

I'm considering making my current P4 rig in to a new Fileserver/Download Box/Seti Cruncher to replace my ageing P3 1GHz Box. So I can get me a Conroe setup.

My P3 rig is cooled passively and is virtually silent. I need my P4 to be the exact same as I work in the same room as it…. will this lot do the job?

Use Scythe Ninja Plus Heatpipe CPU Cooler without the fan, to replace the stock intel cooler.

Use Zalman ZM-NBF47 Fanless Northbridge Cooler to replace the northbridge fan on my abit ic7-g motherboard.

Then put the whole lot in a Antec SLK3000B Midi Tower Case, with Acoustic Matting

What do you reckon?

I reckon you's got yourself a little oven there..............you will need at the VERY least a silent fan blowing over the heatsink, a 120mm fan at 1400rpm or something. P4's run HOT and not at all as cool as a P3 im afraid, you could poss underclock the p4 as well and lower its voltage if the board permits

Had a feeling that could be the case, I thought Scythe were a bit optimistic when they claim you can run any northwood p4 silently.

What would you recommend instead?

Something like a P4 1.6a/1.8a would be a good bet. You should be fine with a big copper heatsink and a low RPM 120mm fan blowing across it.

That's a bit of a generalisation, it was only the later ones (Prescott et al) that outputted silly amounts of heat.

I was trying to do something similar with my A64 server. For the few days that the server actually worked (board died), I undervolted the cpu to 1.175V at 1.8Ghz and it could run passively

You could try throttling back your FSB from say 800 to maybe 533, drop the voltage and see how it runs passively?

The Ninja comes with a fan... use it

Im sure at low speeds it will be nice and quiet.
