Fanless P4 ?

[dZeus]

the future client was the one I meant

[az]

Thought so

It's too expensive and too unflexible for me. When I own my own business though, this thing will sure be sitting on my glass desk

the future client is nice, i bet it is very espensive though. i'm about to build sth. like that myself for my linux server (see sig). just with no cdrom slot, only power button, one led and MAYBE LCD, but rather not. i already found a company that makes custom front/back panels from brushed aluminium (in all colors) for just a few euro (~10€).

the setup will be completely fanless, the VIA C3 doesn't even get handwarm with a small passive heatsink. once the 100GB+ barracudas come out i will replace both 80GB disks with one of them (i dont really need that RAID anymore). at the moment the whole thing is in a shoebox

in the end it will look similar to this:

or this (terratec mp3o):

Totally fanless? No PSU fan?

How do you want to keep the HDD from overheating, and do you think you can cool the C3 passively without ANY airflow, and with relatively high temps in the case?

The FutureClient with a C3 costs 1400 EUR

[thop]

yes on all 3 questions
the C3 uses less than 8W and could even run without a heatsink for hours, maybe days. the passive HS that came with it looks like an old 486 heatsink and it really just gets handwarm. the PSU is a mATX 110W from Samsung, those Barracudas stay quite cold, but i will put a big passive HS the size of the HD on it (available for some € at conrad ).
at the moment the shoebox is open (and in another room), because of those 2 IBM 80GB disks.
if there will be a heat problem i put a 80mm fan at 5V at the back, but i dont think it will be necessary. there will be small ventilation openings in the back though.

Keep me updated!

I saw the 800MHz C3 quoted at 6.7W.

[K6-III]

Has anyone tried overclocking the C3???

[UtwigMU]

Fanless P4 is possible. I saw people bragging about running 1.X GHz Willamette without heatsink.

The only problem would be degraded performance due to throttling.

[az]

The 2.53 GHz from Deltatronic won't throttle. OK, it will, if you keep CPU utilisation at 100% for a few hours. But that shouldn't happen in everyday use - besides, it will only throttle for a short time, cool down, and then clock up again.

mutz: damn, where did you get large version of my highschool pic


back on topic, you could also get one of these :

Its a heatpipe heatsink used by Shuttle in their backbone mini-systems. It has one quiet fan (GASP!), but you could second that as a case-fan, so it still classifies as fanless imho

[az]

No-no, a case fan is a fan! That's absolutely not fanless!

It might be very quiet, but I think there's a world of difference between very quiet and emitting no noise at all (which computers can't achieve, lest you get yourself a HUGE ramdisk and mirror your HD on it, then shut it down - which is just not cost sensitive ).

But thanks for the link anyway

It's about $1500 for 1GB, $10000 for 8GB. But it qualifies.

Err well if you want a completely fanless system dont dream about P4 and 100GB 7200 RPM disks then. Lets remain realistic

[Wombat]

P4 is completely doable, and my 80GB Maxtors are not too warm. I've seen fanless PSUs up to 220W.
