7970 / R9 280X LN2 MOS Heatsink - Effect and Warranty...

Im curious as to whether people have fitted the supplied heatsink, if so, did it bring the temperature of the VRM (?) down effectively/at all?

Then, would fitting this then affect the warranty on the card, even though its been supplied by the manufacturer... A few hours gaming will have my VRM1 at about 65C, VRM2 stays at 27C. VRM1 will eventually stay at a higher temp than the GPU... and we're not in Summer yet...

Theoretically if you start taking apart your card, it will loose it's warranty... even if that LN2 heatsink is included in the original package... - practically, however, you can take apart your cart and put it back together without any problems... just need some experience to not scratch it or do other visible damages...

Now, a question: how did you cool the GPU while that LN2 heatsink was mounted?

The point of that sink is to be used only when you are on LN2

And if you use LN2 you for sure do not have a warranty any more. 😄 😄

ah hah... further digging tells me Im not requiring it... though thank you all for the replies..

Still, how does one keep the VRM temps down, while on air...?

I am sure the VRM's do just fine with the the stock solution..

if you do high overclocking (removing stock cooler), add a high preformance fan, and point it at the VRM's heatsink..

On air your VRMs are never going to get as hot as when you are pushing 1.6volts into a core on LN2 mate. Never 😄 😄

BTW if running crossfite then it go overheat in 30sek at full load Without overclocking... Tested. Cos of that u need to take some space between GPUs, for that u need PCIe extender but then u need to rebuild yours case or build rig...
Other one u need to take air outside.... at Finland outside now about -4C it cools GPU with OEM fans realy fast and cheap.
Now running 1x Gigabyte R9 280x at load 95% (case) 65C rpm 3000
And 3x Gigabyte R9 280x at load 99% temp 69C rpm 3300, 72C rpm 3400, 71C rpm 3400 (rig)

add water block to the gpu cores, put the radiator outdoors and the fun begin

By adding air, the way you do it, isnt going to give you much in terms of overclocking range, the only thing getting cold is you bro..

You need to cut those temps by half ( at least), to be able to push it to another level

If i overclock i do it with water 😜 look at my gallery.
Btw if u put rad outside gpu block will be realy wet, tested gpu dosnt like water on it XD
But if u remove factory cooler then waranty is off...
Ah btw soon will see how much cooler i can get 3x r9 280x with cold air 😛 w8 and see XD
