CPU temps for water cooling - Page 2

post #11 of 14
It is important to tell others your ambient temp when you want them to evaluate your cooling system performance.Even without that info I am not suprised (in fact rather impressed) that a single 120mm radiator can bring a i7-2700@4.8 into the 70C range at full load.For better (I achieve 50-53C room ambient 80F with a i7-970@4,05) you need more radiator and matching fans.You are doing pretty good for what you have.

EDIT: the issue is not the tubing I.D (the internal dimension). Sure 1/4 is small,but it is adaquate for reasonable flow rates.It is not the size I would pick if I was starting from scratch with a custom loop though.

So your telling me that 70'c is good for it running at 4.8GHz...Well near mid 70's after around 15-20 mins burn testing at 100% load. It's got a dual 120mm fan setup and 240mm radiator.

70C is not good but tolerable,mid 70'sC not good but no damage will result from it. I am not saying leave things alone but I do not think 70C (again no ambient given) indicates something is assembled wrong.You need a bigger radiator and matching fans to drop that temp

I really don't know which other radiator/fan combination I could use and try out, I was thinking Corsair H100 to see if there's any difference. Even if it was by 3-5'c I would be happy. And for the room temperature I'm pretty unsure about that, maybe around 12-17'c. Not accurate but it's a start. I'm glad it ain't hit anything above 75'c.
