Hi,

I've just invested in a new system, the guts are below, I have a 140mm Xigmatek XLF-X1453LED Fan blowing in on the front of the case an Eco A.L.C. for the CPU with the fan on the radiator blowing out of the rear of the case and the 120mm fan that comes with the CoolerMaster case blowing in at the top of the case, I've also blocked the empty fan sections.

From boot to idle the temps are between 38-40ºC, under load it's between 58-63ºC.

My question is, should I be expecting more from the Eco or are the temp as expected with liquid cooling?

Code: 
Intel Core i5-2500K 3.30GHz Processor
Asus Sabertooth P67 Socket 1155 Motherboard
Corsair 8GB 1866MHz CL9 DDR3 Vengeance Memory Two Module Kit
Asus GeForce GTX 550 Ti 1GB
Cooler Master Elite 430 Black Tower Case
Coolit Systems Eco A.L.C Watercooling System

They look fine for me. It's the load temps you should be interested in. My idea temps are:

And load:

And thats with custom water. My load temps are in the late 60's @ 4.8 @ 1.44vcore.

I'm not familar with the CPU cooler, but i have similar ambient temps and with stock intel cooler my idle is around 30-32c. Do you have speedstep disabled?
 
Just built my new system with the same cpu and cooler. (Board is Msi , case is nzxt phantom and gpu is a 470 cooled by a Zalman cooler.)

Assuming that your running at stock your temps are approx 10c higher across the board than mine.(Running at stock at the moment) Idle - as I'm writing this 24/26c & Load (Ran Intel Burn Test Standard 'freeze' test 5 runs- did this a few minutes ago)max 41/43c.

The cpu fan cooling I leave to the motherboard using PWM.

BUT your temps are, from all that I've read fine!!

I have a lot more cooling fans than yours (140 x1 +2 x 120 intake front and side + 1 x 200 side intake + 2 x 200 exhaust in roof and the Apache exhausting from the cpu) and therefore the systems are not directly comparable but I would ,in your situation, be looking to lower my temps.

Suggestions :-
1. Blocking vents/vacant fan positions can increase temps - it can have the effect of keeping heat in, you may be better served leaving them open.
2. Would def. recommend changing the fan on the coolit eco to an Apache ( I found that the Apache runs less noisily and cools better - in my system at least). - If you have room you could try a push/pull system (This did not work for me as it interfered with both intake fan in the side and the exhaust fan in the top - beside which the temp. reduction was minimal).
3.Try the top fan as an exhaust fan rather than an intake.
4. If all else fails you could try re-installing the coolit - but use a better thermal paste e.g mx3.

I am afraid that the only way to find what is best for your system is to experiment a little - Personally I'd try and get a good 'cool' airflow running though the case by putting in place 1 & 3 above and def. change to an Apache fan (Vipers I've read are the best but I'm using the original bog standard one)- I'd leave 4 until later and might never bother if the other steps worked.

Good luck! (I hope the above helps.)
 
Just noticed your CPU-Z Core v reading - if your running stock 1.3+v is rather high imo! ( Mine does not go over 1.208v when running Burn Test.)

The greater voltage might also explain your higher temps. - I have no experience of your motherboard so cannot help further, hopefully someone who has can.
 
mate have you disable speed step or something?

is your i5 running at 3.7ghz and 1.312v even at idle?

maybe re-enable speed step so it should drop the core speed down to 1600mhz when not doing anything and cool down a wee bit

your load temps at 1.3v dont seem way out, but im using cheap 21 quid cooler and getting similar results, i'd thought with watercooling you would be good 4-5C cooler at load.

under 2-3 hour stress testing (prime 95) i hit max 62C putting 1.3v through my chip


Also you say "under load" were you running some sort of stability burn test that creates lots of heat? or was it just during gaming etc?
 
Those temps are fine.

I've built 3 sandy bridge rigs and they've all had varying temps and voltages.

For example the 2500K Rig in my sig was built for a respectable clock using minimal voltages with speedstep enabled etc... Yet running at 4.4Ghz and using only 1.19V - my idle temps are 28 to 38 and 65 to 70 under load. Out of the 3, almost identical, rigs built this CPU runs at the lowest voltage and yet runs the hottest...

Like yours, this is well withing tolerance - some chips just run warmer than others and some of it's down to heat sensor discrepancies (all things are not equal from board to board and chip to chip), plus case, cooling etc - which is why you get a lot of varying temp results with very similar setups.

It's comforting to have really low temps but the temps you have, like mine, are absolutley fine.

EDIT: HAve you tried dropping your core voltage?

I think I found the cause, the 'AI OC Tweaker' built into the ASUS BIOS was set to an XMP performance profile raising my core voltage, I've set this to auto and it's dropped the DDR speed to 1333 from 1866 and the voltage on the CPU is now varying when idle and under load with prime.

Idle temps are now 35-38 and under load don't go above 53

thanks for your replies!
