The coolest thing on earth is the Voodoo 5, is it not?

I’ve just added a small fan to the heatsink of my Voodoo3 2000 and got some fantastic results out of it - seems 100% stable at the 183mhz clock speed of the 3500 and I haven’t tried pushing it any further yet. 3Dmark scores are up by around 1/3 which is pretty crazy.

This has got me thinking about the puny heatsinks and fans on my Voodoo5 - it gets very very hot to the touch even at stock speeds. Much more so than the modified V3 even though that has a huge overclock on it. I’m not necessarily after higher clock speeds on the V5 but lower temps would be nice. Anyone got any tips for improving the cooling on one? Any tips for removing the old heatsinks welcome too, I’m nervous to do it!

My idea was to use some heatsinks like this https://rover.ebay.com/rover/0/0/0?mpre=https … %2F113022989575 and reattach the original fans - they should be much larger in surface area being a fair bit taller and about 5mm wider in each direction, and also keep a nice stock-ish look to the card as I’m not a fan of some of the huge heatsinks I’ve seen some people bolt on - any thoughts?

Hello, I did something that might seem lightly like an overkill, I tore apart one of my dead passively cooled radeon cards, got rid of old fans and attached this with thermal grease using rubber bands, might not be the best option but its maxed on 42 celsius.

Haha certainly some “interesting” suggestions 😁

I know the cards were designed to run as hot as they do but surely at the age they are now it would increase their lifespan making them run a bit cooler? Just nervous getting the heatsinks off

Not sure if I want to go the whole hog and slap a Radeon cooler on there haha but I quite like my idea of just taller heatsinks with more fins + the stock fans, has to make some difference right? while retaining most of the stock appearance

I think the best solution is to underclock it a bit and to compensate with a faster cpu.

I don't think that's how that works. If you are fill rate or bandwidth limited, a faster CPU will do nothing.

It is well known that the voodoo 5500 benefits from a faster proceasor than what was available when the product was released.

This is true but surely with a faster CPU you’re working the card harder making it run hotter instead of cooler? 😐

I’m already running it with a 1.4ghz Tualatin but it seems by adding a faster CPU and then underclocking the card you’d just end up back where you started performance and heat wise?

People here have swapped the fans, admittedly 1/2 the time that's to reduce noise but modern fans move more air then the nothing special ones the v5 came with.
The usual tricks to break glued on heatsinks apply here. My favourite is freeze the card and try. it is scary though!

I’ve not seen any evidence that a faster cpu would cause a voodoo 5500 to run hotter, but I agree that a 1.4ghz Tualatin is fast enough.
