Need help trying to find solution for dealing with Asus Strix rx 480's temps

post #1 of 4
Thread Starter 
I'm was planning on switch the cooler to a universial AIO water cooler but ASUS of course doesn't make things easy and ran into a wall with trying to find a solution that that works on cooling the VRMs since there isn't an easy way to mount them if there is a way at all. So I'm asking if anyone who's been down this road or knows of something that would work for this problem could point me in the right direction.

You can add a fan shroud, thermal pads like Fujipoli and heat sinks to the VRMs in concert with the AIO.

I don't see a point to this unless you have a fully watercooled system.

The ASUS STRIX RX 480 uses a nonreference PCB and already has one of the largest heatsinks and the main heatsink cools the VRM.

The only potential issues I have seen with the STRIX RX 480 are the memory cooling and also the 5th heatpipe's contact with the CPU core (both are fixed on the RX 580 STRIX , see https://www.bit-tech.net/hardware/graphics/2017/04/18/asus-radeon-rx-580-strix-gaming-top-oc/2) , see http://www.tomshardware.co.uk/amd-radeon-rx-480-graphics-card-roundup,review-33851-6.html.

The cheap way to deal with this AIO project you propose would be a fan bracket and copper or aluminum VRM heatsinks that attach with thermal adhesive

Something like http://www.aquatuning.us/air-cooling/passive-coolers/19418/enzotech-mosfet-kuehler-mos-c1-le-passiv-black?c=6633 or https://www.newegg.com/Product/Product.aspx?Item=N82E16835708011

The enzotech MOS-C1 and MOS-C1LE have a 6.5mm x 6.5mm footprint , which s the proper size for covering the GPU VRM mosfets (IR3555) 6x6mm on the board.


There's also alphacool mosfet heatsinks made from aluminum without adhesive included (https://www.newegg.com/Product/Product.aspx?Item=9SIA9F93H90425) that are 7x7mm footprint that are much cheaper. Keep in mind aluminum has about half the thermal conductivity of copper though. You probably would need to buy something like Arctic Alumina (https://www.newegg.com/Product/Product.aspx?Item=N82E16835100014).


For the RAM, if you feel it necessary you might opt for the cheaper aluminum VRAM heatsinks
https://www.newegg.com/Product/Product.aspx?Item=9SIA9F93GK7369
https://www.newegg.com/Product/Product.aspx?Item=9SIA9F93PU7382 or http://www.aquatuning.us/air-cooling/passive-coolers/13663/alphacool-gpu-ram-aluminium-heatsinks-15x15mm-black-10-stk.
http://www.aquatuning.us/air-cooling/passive-coolers/19416/enzotech-ram-kuehler-bmr-c1-le-high-profile-passiv-black
https://www.newegg.com/Product/Product.aspx?Item=9SIA85V3V36803

The NZXT Kraken G10 bracket comes with space for a fan over the VRM by the way.

I do have a full loop but I haven't and don't intend on transferring it over from the my old sys to this new build was using additives and it was just too much going on in the blocks so I decided to go straight water. I gotten all new parts and tubing for a new loop save for the pump/radiator/res was holding out for ek's mlc but just found out that got delayed a couple weeks ago so I'm moving on with a temp setup. I picked up a generic vrm kit from Arctic and roll of double-sided thermal tape(@1.3w/m-K, I think it might be a mistake tho the enzotech sinks you link come with adhesive that has .6w/m-k applied so I just guess I'm being a little pessimistic) to temps look like. As for the ram there weren't any ramsinks on them to begin with and were just being aircooled, I picked up some coppersinks just in case.

I'd did look at the kraken bracket but I bring myself to buy it, with it costing 40 bucks.
