Hi, I am just wondering if there is a way for me to mod my gtx 970 (palit oem blower) to get some good temps while still being quiet? I have been looking for aftermarket coolers but they just aren't available in the UK anymore. Could I possibly use a cpu cooler for my gtx 970 as, the stock heatsink is tiny.
Plenty of ways. Strapping a CPU heatsink isn't the simplest due to the differing hole spacings between common CPU coolers and GPUs. Certainly possible. Might look into modding a Noctua NH-L12S, be quiet! Shadow Rock LP, or Scythe Shuriken on there.
Kraken G12 and Asetek style AIO? Designed for GPU cooling, and certainly compatible with reference GTX970.
The only non-watercooled cooler I can think of that would fit is the ARCTIC COOLING ACCELERO XTREME III
What you could do that would be cheaper is check ebay, etc for a used cooler with the same bolt pattern, but a better cooling solution. Another solution that might be cheap would be better case airflow. If your case has poor airflow a $50 case and $30 worth of fans might make a bigger difference than any non-watercooled option would if your airflow is bad right now.
