Ive done it! I have successfully managed to remove my Tbred's Fan. Then again, I do have a side mounted 80mm case fan blowing directly onto the HS. nonetheless, Im proud to have a much quiter comp, with only a small sacrifice in temps (36/42C Idle/Load). Next stage is to buy a more effective HS, im currently using an aluminium coolermaster, I think a fanless Volcano 7 is even an alpha would be much more effective, possibly meaning that I dont even need a casefan!
btw I also have a pasive cooled processor (in one of my other computers)... An intel pentium II... HeHe. It has a gigantic heatsink, I think its copper... don't quite remember. Even that processor has a case fan blowing over the heatsink.
Ive recently put the 12v casefan on 7v, so now its basically silent, and only moves a very small amount of air (not exactly sure of cfm). My temps are 37/45C idle/load. With the fan on 12v they were around 32/41C.
TechTV's, "Screensavers," featured Yoshi's Quiet PC (P4 based). Just 8 dBA (14 dba for frequencies below 100 Hz), tested in a listening room at Dolby Labs.
Pretty common stuff. Sound deadening material, quiet HSF, video heatpipe, soft-mounted, speed controlled, and oversized fans. Only slightly unusual things were the fan mufflers and the mod'd power supply.
The PC is kind of a commerical for Zalman (and I'm not a big fan of Zalman coolers) but I'd never seen the CNPS7000-Cu, a 109 mm orb-like cooler. It's massive and weighs in at 773 grams. The Zalman video heatpipe I had seen prevously.
Personally, I'd probably prefer something like the Spire Falconrock II/Speeze RaptorCool 1 which is a massive copper/aluminum hybrid. (I'm thinking about your idea, though).
Well, Ive just managed to sell a P2 system for £100 so a New HSF may be what Im looking for. Then again, an nforce2 mobo would be nice in order to get those higher multipliers and more performance than my SiS745 mobo. Ahh, but i also need to replace my 5400RPM 20GB PIO hard disk.... So much to upgrade.
I think I really need to upgrade the HDD and mobo together (to save 2 formats/reinstalls), but that would cost a lot of money (about £180 probably). Maybe I should go for the HSF first, because that would only cost about £25, and I could also try and get a 120mm Casefan to replace my 80mm version (a little bit of modding required). hmmmm... I'll have to think about this.
