Corsair H90, odd temperatures?

[JTyran]

I just transplanted my PC from an Antec 1200 to a Corsair 760T, I left the top panel on because I liked the clean lines of the case. In the old case my standard clock speed i7 3770K ran at 28-30°C with the stock Intel heatsink, probably due to the huge airflow.

I knew the new case would have less airflow in CFM but with the open nature of the case its less restricted, to take the CPU heat out of the case I fitted a Corsair Hydro Series H90 at the cases 140mm fan mount as an exhaust.

I never used liquid cooling before but the temperatures strike me as odd, both Asus AI Suite and Speed Fan show almost the same temperature readings. Idle the CPU sits at around 35°C, it fluctuates up and down a couple of degrees but that is the general "average". Now I expected the temperatures might be higher with the reduced airflow but with the liquid cooling I expected it to be better than the stock cooler.

Now where it seems really odd to me is when under load the CPU temperature only goes up to around 40-45°C, again maybe a degree or two higher but thats where it sits generally. Even under 100% CPU load with stress test software the temps stay around there but that seems low considering the high looking idle temperatures, is this behaviour normal or is there something that is causing this? Have I set it up wrong or do I need better temperature logging software? Apologies if this is just my inexperience with liquid CPU cooling but getting to the bottom of this would set my mind at rest.

The PC is running at stock settings with no overclock and the H90s pump is connected to the CPU fan header, I set the fan profile to "turbo" in the BIOS as well.

PC;

Asus P8Z77-V LX
Intel Ivy Bridge i7 3770K
Asus GTX 780 Direct CUII (slight factory OC)
Corsair RM850 (installed upside down with external air intake)

Thats all the components that have the most impact on heat output, all factory settings and no overclocking.

There's no point quoting idle temperatures, they don't mean anything. That load temperature is more than fine. What were you getting at load before?
Also, unistall AI suite, its temperature readings are always well off and it interferes with other temperature monitoring applications, making them give false readings

Also stock settings means jack. You need to manually set your stuff dude.

Auto = n0000b

Why bother? I don't see why not overclocking makes me a "noob" so you can keep you judgemental insults to yourself.

Idle temps are more related to your ambient temperature than anything else so that would be an interesting thing to know. Since both ambient and load temps are low your cooler is effectively dissipating the heat and you should not worry.
Also what Tim is saying is not that you should overclock but that at your current clock most motherboards come configured in auto. This usually has a significantly higher voltage than is needed to ensure stability. They don't care much about temps since they are way below the max at 100 C. Therefore a way to reduce your idle temps would be to find the lowest stable voltage for your current clock and set it manually. This would likely reduce your overall temps. Even setting intel's recommended voltage for your processor manually would likely be of benefit.
It could also be a poor mount so consider re setting the processor but it is most likely related to poor air flow through the new case. A detailed explanation on fan position may help us give you better advice.
Finally you know TTL kind of owns this website right? He is just trying to help.

No need to be insulting about it though, I will readily admit my lack of experience with things I don't know about but there is no need for anyone to be rude about it whether they run a site or not. You explained the situation without resorting to insults, its not like anyone has to grovel to anyone or anything just a little common courtesy is nice.

As for a detailed explanation? No disrespect to you but I don't think I will bother wasting my time, a ban is probably incoming anyway. I maybe inexperienced with fiddling with voltages but I know my way around the internet well enough to understand what happens when you go against the gospel of admin/owner that thinks owning/running a website gives them a big dick and have the right to go slapping people across the face with it.

i found with my h100i my idles were slightly above what my stock cooler gave, im guessing due to the heat soaking on the rad and difference in ambiance temps etc... as your is now pushing air out the back of the machine it could be being restricted by a wall allowing more heat in that area by the wall.

But once temps rose due to use not just on games and benchmarks but even day to day stuff like the interwebs and music playing i found i got lower temps that the stock cooling gave.

"undervolting" as the guys have mentioned can give you a bit better temps and longer life for your CPU, plus dropping your power pulling.

I think TTL only mentions OC'ing due to the fact you have forked out some lovely kit and its not being used to it potential.

IF ya not OC'ing ya 3770k care to swap for a 3770 non k lol
