So I just installed a cpu water cooling solution. I have the XSPC Rasa RX240 with a D5 pump. On air cooling my min temp was ~30C, on water it is ~40C. Now while the idle temp is higher, the max temp on air was ~70, while the max temp now is below 60. Is there a problem here or is a idle temp of 40C acceptable?
Watercooling is better when the temperature rises, that is normal, unless you are using compression equipment to lower the water temperature you won't see idle gains but your load temperatures will be at least 25% lower. You will also be able to push the vCore over 1.5v with a good waterloop cooler.
