4870 VRM Sinks

Can anyone recommened some good ramsinks for the VRM's available to the UK, they get ridiculously hot on the 4870 especially when pushing the card while clocking.

enzotech are the best, but any reasonable brand should do, Ive found in the past though the pre-applied thermal tape that come with most is pants (and thats being kind) use your own TIM

it depends which cooler you are using.

Twin turbo. I'm wondering if this little sucker will fit with it, it's just been released and I'm yet to find anyone that's used one. Available for a measly fiver.

Cheers for that. Have been looking for exactly something like that for my HD 4890 for a long time.

I think I'll have to cancel my order, unfortunately just found out that it may not clear the twin turbo, so it's back to the drawing board and trying to cool these bloody VRM's

Really hope that they'll fix this on the 5870, the 4870 is a way too hot card, and therefore extremely noisy on stock cooling :/ The VRMs are especially bad

THERMALRIGHT TO THE RESCUE!

Yea I'm interested in that, it's a new product aswell though and is yet to come on sale anywhere.

but yea I hope ATi address this VRM issue and use some better chips that don't heat up as much.

It's a real pain in the **** to have super cool GPU temps for it to be spoilt by some vregs.

Thats one crazy/ingenious VRM cooler. Id have a side panel fan and so this could be ideal. A shame that it will probably cost £20.

The twin turbo (assuming the arctic cooling one) comes with VRM heatsinks, no need for aftermarket ones.

If you already have the twin turbo but don't think the included ones are up to the job then consider this another +1 for Enzotech.

They aren't up to the job, I get better performance with the stock backplate for the vrms mixed with twin turbo

anyone know if that thermalright vrm cooler is compatible with the Akasa Vortexx neo? Any recommendations for a vrm cooler that is compatible with the akasa cooler?

the zalman ZM-RHS70 vrm heatsink works with twin turbo. I have fitted it on 1 myself it just sits snugly with the fins on the twin turbo and it really cools the vrms down a lot.

Tom|Nbk · 27 Aug 2009 at 01:23

Nice one thanks for letting me know, appreciate that. Might look into that!

What sort of temps are you getting.

I am however, getting the new ATi card when it's out so may leave be.

tommythetim · 27 Aug 2009 at 02:02

according to gpuz temps before zalman vrm, i was getting extreme temps up to 139, and i thought my card was going to fry. With the zalman the vrms never went above 80 under load. Big difference.

I would say it is. Looking at the technical drawing on Thermalrights website the actual heatsink is only 9mm thick and i have around 12mm under my Vortexx neo.

Thanks for the info...I think I may not bother though and sell off the 4890 to wait for the 58xx series
