Water cooler in a Thermaltake level 10 GTS

Idle 85F = around 30C
Load 100F = 37C

...these are great temps both idle and load........ what is the concern?

^As the Rubix pointed out, those are great temperatures to have. I dont even get that good load temps on my water-cooled rig.

If you are a casual user, learnt how to build a computer, did it and left it at that. I wouldnt suggest anything more than a H100i. Custom water-cooling requires a lot of thought and maintanence.

Well i asked my cousin (who bulit his computer) and complained that my cpu and case temp were to hot. He gets 60f idle and under 80f under load. i dont know the specs on his but hes had his computer for 2 years now.
I was just worried that my computer ran too hot.
thanks guys for setting me straight  

Sounds like a case airflow issue, not necessarily a cooler issue. Open the side of the case and blow a large fan on highest speed into the case and measure temps. If they drop significantly (5C+) you have a case airflow issue. If they remain the same, you have a cooler issue.

Walleater, did you get a h100i for your thermaltake GTS? And does it fit? I've got the same case and now the h100i, but the screw holes in the rad don't line up with the 120mm mounts on the case, the case mounts are about 5mm too far apart, and they also seem to be too low for the rad to clear the motherboard, even if it did fit.
Let me know if you've the same problem or found a solution.

Did you misinterpret your friend thinking he was speaking in Fahrenheit and not Celsius? It is rare for someone, even in the US, to speak of computer temps in Fahrenheit instead of Celsius so I think there may have been a mix up somewhere.

"Case temp" in an L10 is rather deceptive. It's build is designed to comparmentalize and direct airflow in those compartments. So the term case temp... not true full case temp. Each of your massive fans is designed to cool a certain area. you are running well within expected spec for build and usage. IF you do want lower, upgrade fans to higher CFM, and/or small closed loop cooling - But do not expect miracles. maybe a few degrees C delta. Rather than worrying about case temp, what are your chip temps at? Do you have anything covering vents, poor cable management impeding airflow? Accidentally reverse a fan on case build and not running positive case air pressure? Have a fan bearing going bad reducing performance? Dust bunnies from hell wreaking havoc and planning your demise whilst you sleep? K.I.S.S. in this situation IMHO
