Core i7 2600k Overheating at IDLE

Hi guys,


First off, let me give you some specs:

Intel Core i7 2600k Sandy bridge (Just now bought the corsair H60 watercooling system)
ASRock Extreme4 Gen 3 Mobo
8 GB Corsair DDR3 Ram clocked at 2133
128GB Crucial Sata 3 SSD
2x ASUS GTX 560's SLI
850 W Antec Modular PSU


When I first built the system, I used the stock fan provided from intel.. I noticed in BIOS that the CPU idle temp was 50c, and in windows idle was 45c. At load, the cpu would go above 70c playing battlefield 3. So, I thought, why don't I just buy myself some new thermal compound.. So I bought some Arctic Silver 5 thermal compound, removed the heatsink, removed and applied the thermal compound properly. (Saw three different videos.. Apparently everyone has their own style on how to this.) Put the stock heat sink back on, and there was no temperature change at all...

So, hmm. A few weeks later I decided to buy the Corsair h60 water cooling system. So, i went ahead and installed it. I removed the thermal compound that came stock with the H60 properly, and the compound on my CPU. Applied the Arctic Silver 5 Compound, and installed the radiator in a Push/Pull Configuration with one of my case fans.. Plugged in the pump and fan into the right ports on my mobo and I was ready to go...

Loaded into bios to check my temps.. THE SAME TEMP! IDLES AT 50c with water cooling!!!! I tried a few troubleshooting steps like someone on another forum mentioned that I tilt my Case to let the water flow through initially.. Didn't work..

Then I thought, maybe my BIOS is just reading the tempurature wrong.. So I got the most recent bios update, flashed my bios.. Went back in and it's exactly the same...

I'm at a total loss. I bought this nice watercooling system and it's just running so hot. What else could it be? Is somthing faulty? I'm I just faulty? Did I not eat my Wheaties for breakfast?? AHHHHH

Lol @ Wheaties.

At idle, you will probably see little to no difference between air cooling and water cooling. You will notice a better cooling performance at load though.

P.S. Not to shoot down your purchase, but the H60 is far from a nice water-cooling system.

Others are reporting idle temps with over clocks at less than 30C. Did you over clock your chip? Put too much/little thermal paste?

Hi steadywaters,

Thanks for your reply.

My system is not overclocked at the moment. . I did however try to overclock it to just 4.2, and idle was like 65c.. So I changed it back to default..

Even with the stock fan though, the idle temp should not be around 50c.. Although after installing the water cooling unit, I did notice a 2-3 c difference in windows, but 43c idle in windows is garbage!!!

I have a friend who has a similar build with the H60 and he says he's idling in the 20's and hes at 4.6!!

As far as the thermal paste, I have been reading that it's just a pea size.. So I did just that.. Some say to spread the pea size then add the heat sink, and others say to just smash it with your heatsink so it will not have any air pockets.. I did the latter.

Even though you say the h60 is sub-par, I should at least see some idles in the 30's, or even 20's... at stock.. argh..

Okay, thanks man. I'll try this when I get home from work today. I'll let you know how it goes.

Okay,

here is what core temp is saying.. Seems to be lower in the 40's and maybe a high 30 here and there.. I mean, it's acceptable, but damnit I have water cooling..

You're not idling, that says you're at 3.7ghz (which is a turbo speed, 3 cores at load) @ 1.23v (again a turbo voltage). Do you have some background processes on? Idle should be at 1.6ghz @ ~.95v unless you disabled speedstep. And bios will always be hotter than windows because in bios the cpu is at load state, it can't idle til it gets into windows.

no, I had a few processes running in the background so i guess it's not idle.


I don't understand. If the CPU is in load state in bios, how come i have friends that show the temp in BIOS to be in the 20's? And they have virtually the same setup..

Are you suggesting that my temps are fine?

He's most likely telling you windows idle temps. Also what about room temp?

What voltage is your ram at? If you really want to compare it to your friend's you need to consider every component and every variable. Idles temps really aren't an issue, it's not higher than normal, what's more important is load temp. But if you want to compare both, that's fine.

Okay, here are some specs in the Asrock utility. I have it slightly overclocked to 4.0GHz.. I haven't considered my voltage on my RAM or anything yet.. Not sure what else to look at.

What case do you have? Are you sure fans are all the right direction? Mobo temps are high for 70F roomtemp. I'm at 75F mobo at 26C. I figured your ram was at 1.65v, memory controller is on the cpu. What is your vcore as well as temps of the cpu at load?

I have the Antec 1200. I've double checked the fans and they seem to be in the right direction.. Here are some pics..

What program should I use to see a true load? When I say load, I mean when I'm gaming.. (Specifically battlefield 3 on ultra settings).. I saw that the temps were getting into the med 70c's which is really hot.. All the case fans are on low though...

Wow!

During the stress test it was in the 90's and was still climbing!! I stopped it because I didn't want it to get to hot.. This is rediculas...

Voltages are not high enough to cause such temps (although 1.34v can get 4.7ghz) so it's either not mounted correctly, you can check this by looking at the thermal paste footprint, or the h60 is faulty/not working.

Well, Here's today's attempts..

Here is a look at the current thermal paste on both the CPU and Pump.

I texted this to a buddy of mine and he said it was a little to much.. So I took it off and re applied the Arctic Silver 5 thermal compound... Now I'm seeing even higher tempatures, so something is faulty.



I did a live chat with an Intel support tech and he pretty much gave me the same trouble shooting steps that I have been doing, except to try the CPU in another motherboard.. Which I do not have a second Socket 1155 hanging around... So this is either the CPU or the motherboard..

No, its the cooler. The cpu is obviously fine and a hot cpu can't be caused by a mobo. The h60 is shitty in the first place.

Well, should I just try the stock heat sink again and see what happens?

Sure. Make sure you set it back to stock speeds.

Okay, everything is back to stock.. Stock speeds, and stock fan.. Didn't have much time to look at the temps in windows this morning, but I quickly glanced in BiOS and the temps were exactly the same.. Says it's 55c - 60c in bios.. I think this is still too high for the stock fan..

I went ahead and RMA'd the stupid watercooling..

Downclock you ram to 1.5v, this is stock. Remember thermal paste is just filling in the tiny gaps, so it will be a thin layer when you remove the hsf.

Hey,

Well, i got the RMA back installed it with the stock thermal paste this time, and it work ALOT better than the other H60. It must have been a faulty pump or something. I have it now overclocked to 4.2GHz (No Turboboost) and my CPU idles in the low 30's now, during gaming I will see it in the mid to high 50's, and sometimes low 60's Which is acceptable and better than the stock fan.. Still not Ideal, but at this point I'll just take it a run with it.. I still would like to see better temps though.. As I bought the h60 anticipating to OC close to 5GHz. Apparently this is not feasible with my set up..

I'll run prime95 with it overclocked and see what temps I get..

K1114, I tried downclocking my ram to 1.5v, but didn't notice a difference. So I set it back to 1.65v.
