I'm in the process of converting my "work" PC into a near silent system. Currently the only pieces in it the make noise are a fan on the power regulators (problem area on early Abit boards running hot, hence the fan) and the V5500 fans.

I'm thinking that a pair of V-3000 heatsinks on the V-5500 should work rather well considering that the VSA-100 chips run at the same clock speed.

I have always been of the opinion that the only reason that the VSA-100 chips had fans were for marketing reasons. Remember the flack 3dfx got from the press on the Voodoo 3?

Has anyone tried this? Anyone have some dead V-3000 cards with a heatsinks I could buy?

i remember i've started the same question some time ago..here it is:

dunno about the v3 coolers, but they even run too hot on a v3 3000..so i see no reason to use them as you want a silent pc (w/ these coolers you'd need additional fans)

Well since most V-3000 and V-3500 are still running just fine at their default speeds of 166 & 183 mhz I would think "running too hot" is subjective. The Falcon Northwest cards were even clocked at 200 mhz with no active cooling.

well maybe you could put a probe on the v3 and on the v5 to see how hot they really get, my v5 would scorch my finger on the back, the front has to get plenty warm :-/

Just what I planned on doing, I already have a V3 up and running a loop with the probe in place.

Took all the fans I had and ran them all to find the quietest one and stuck that on the power regulators, all I have to do now is find a pair of V3-3000 heatsinks. Except for the V-5500 fans I can't hear the thing running.

Man I just sold three on ebay for change 2 weeks ago too! Never fails....

Turok demo, temp taken back of card after 1 hour-

V3-2000 at 143 mhz = 124F
V-5500 at 166 mhz with 4x "AA" enabled = 115F

I think we can all agree that the V3 temps would be higher is a V-3000 or 3500 were tested.

V3 was tested with an open board on the bench, V5 in a sealed, but large case.

Now to find those heatsinks...

You could fit some Zalman heatpipe coolers.

Or water cool.

Or build your own heatsinks out of sheet copper.

Not in the budget, don't like moving parts (prone to failure), to much time & funds to invest in a "work" pc.

A pair of V3000 heatsinks would work perfect and they are a dime a dozen.

Urm, no moving parts required!  ::)

You can use passive water cooling for the voodoo 5, provided the card is mounted vertical (you will need a desktop case).

Making your own air heatsinks is dirt cheap.

Anyways, an aircooled system has moving parts- they're called fans aren't they?

Watercooled systems generaly require pumps, pumps and fittings fail, not to mention I'm not going to invest in a watercooled system for a P3-700.

No room on the desk and I alreay have a full size tower.

Which take time, of which I have an amazing lack of.

Self-employment, a home, a number of cars and projects and a 3.5 year old robs it all in a hurry.
