Cooling solution needed - Gigabyte gtx460

post #1 of 6
Thread Starter 
I upgraded to a water loop yesterday and my gtx460 overclocks amazingly with the XSPC Universal GPU block. At 900mhz, the core temp never exceeds 30c while benchmarking in 3dmark06. Memory is well cooled too, with copper heatsinks.

While everything looks and performs great, the VRM heatsink on the card is running red hot...even with mild overclocks. Anyone out there know of a good replacement for that heatsink or any way to keep it cool?

Thanks in advance.

you could get a block for the VRM and hook it up to ur loop. or u can get a 40mm fan and place it on top of the heatsink.

From the pic, I think you are using EnzoTech's BCC9 to cool the memory already.

I reckon, the full copper EnzoTech's MOS-C1 should be a good alternative. A multipack contains 10 pieces while you will need nine (see red circle in pic).

I ended up taking one of the 90mm fans out of the stock gigabyte cooler and mounting it above the vrm heat sink. It doesnt blow a ton of air, but it is quiet and has helped cool the heat sink, pcb and memory on that side of the card. Plus, it plugged into the fan input on the card itself so it looks clean.

Id put more precedence on cooling the VRM / Mosfets over the ram chips. How are those ram sinks sticking? I had issues with them before, fixed the issue by putting small dots of super clue on the corners of the cram chips.
