Hey everyone,

I have a custom built lc dual loop setup for my cpu and gpu's respectively. My temps for my un-overclocked GPU's dropped from 80C to max 45C. My question pertains to my CPU (3960X) which runs at around 70C running at 4.7 GHz and 1.360 Vc. i keep this OC 24/7 as it is my daily computer. My loop has a single 240mm rad and ek supremacy waterblock. Are these temps normal? I have reseated my block, and my temps did not change.

What kind of radiator and fans speed are you running? But for me, temperature is right, maybe just a little bit hot, but six core sandy's run hot.

I am running alphacool XT45 rad with dual noiseblocker 1400 rpm fans in a push in configuration.

Forgot to ask, your ambient temps? and by 70° you mean at full load right? smile.gif

Ambient Temps are between 65-68F, and yes, 70C at full load for an hour.

I think you are probably 5° over... I was checking your rig and something caught my attention, it's that air in your loop? In the red circles or just reflection?

That probably is air, but that is an old picture before my t-lines had time to work. There is no air now.

You have a CPU OC'ed from 3.3 to 4.7 that has a TJMax of 91C and after one hour at full load you are at 70C. I would say you are doing great. You have 21C headroom after a decent OC. Without knowing your delta T on your water in / out and water out / ambient it is hard to say if you could do any better. Remember there is no set temp for water cooling your rig. It depends on how good your fans are at pushing air through your rad, dissipation quality of your rad, room temp, quality of the mount, etc.

You should be looking for two things:

1) Is the temp at full load at your OC well below TJMax - yes yours is, you can stop here, the rest doesn't matter as better load temps will not improve your OC.

2) Is the water / air delta < 5C - then you cannot do anything but lower room ambient to get better cooling, your loop is about as efficient as it can get.

As a side note you can look at water / water delta to see how efficient your rads are working. in conjunction with the air / water delta.
