Corsair H110 De-lidded i7 3770K Temps?

post #1 of 7
Thread Starter 
Corsair H110 AIO CPU Cooler
I7 3770K Overlock to 4.5GHz with 1.18v in BIOS ( but in CPU-Z it shows the voltage as 1.20v on idle and jumps to 1.21 on 100% load don’t know why it’s showing different voltage to the one in the BIOS )

Room Temperature 21.3c
Run Prime95 Small FFT’s for 12 hours
Highest temp I got on 1 core was 60c
On all 4 cores was between 55c to 59c



I wanted to know are the temps above ok for a de-lidded i7 3770K CPU? The reason why I ask this is that when I bought the i7 3770k brand new I de-lidded it straight away so I don’t know what the temps would have been before de-lidding it. So if someone has seen load temps before and after de-lidding can tell me if my temps are ok? I do understand my overlock will be different to others and the CPU voltage as well but if someone has similar overlock & voltage would help thanks.

Considering the IvyBridge TJMax is 105C I say those temps are really good. The real question is not if the temps are good, but why aren't you sitting @ 5.0GHz right now wink.gif

That's because I tried 4.7Ghz but this needs 1.30V to be stable I mean can you see the jump from 1.18V to 1.30V and that's only a increase of 200MHz I would think to get 5GHz am looking at over 1.50v

You are worried about 1.3v man? You are safe up to 1.5v daily to be entirely honest with you.

Nothing to worry about with those temps.

I had the same temps with my delidded 3770k on a H100i. Those are great temps! Before you delidded your temps would have been in the 90's after an hour of P95. These chips don't start throttling until 105c. After that the computer doesn't even shut off until 120c-130c!!! I never would let mine go above 85c, but I don't have to worry about that. I love delidding!

Sorry to necro on my first post ever on this forum, but I do have an answer to the OP and this thread was never resolved.

I had an issue with my H110. My temps were very poor so I posted with Corsair and made a few changes.

I was running @ 1.25v and clocked @ 4.2ghz. My CPU can do 4.5 @ 1.256v(reported in cpuz) so this was the baseline test. I have an i7 3770k running 16gb of 2400mhz kingston ram.

Here are my system specs currently: Intel i7 3770K 4.5 1.25vcore ~ EVGA ACX SC GTX 780 ~ Corsair H110 AIO Cooler(w/ 2x 140mm BGear Blasters), MX-4 TIM ~ Corsair AX1200 w/ 100.4amps on one +12v rail ~ 16gb (2x8gb) Kingston Beast HyperX DDR3 2400mhz CL11 w/ Kingston cooler ~ Samsung Pro 840 256gb SSD w/ Win 7 Pro 64 Bit + 64gb C300 + 3tb ancillary ~ Asrock Extreme6 Z77 8+4 Phase Motherboard ~ CoolerMaster HAF932 ~ Samsung 32" 1080p 120hz LED Desktop Monitor

So, you may ask what were my results:

Well, initially my CPU was NOT delidded. When I hooked up the H110 vanilla, I was reaching 78C on the hottest core with an ambient temp of 22.2c(72 degrees).

This was only minutely better than my previous push/pull hyper 212 +.

So I asked Corsair what was the deal?!?

Ramguy told me that the cooler seemed to work right and it may be fan configuration.

So I modded my h110. There are no springs, so no way to tighten up the block, except thru shimming. So I did shim the block. I also changed out the thermal paste for IC7, and I also tried MX-4.

Results remained unchanged. Next step was replacing stock fans with BGears Blasters @ max RPM. I also used some gasket paper to properly direct the flow of the fans directly into the rad. I was in a push configuration, pushing hot air into the case.

Even with the fan change I saw little real difference in max temps.

So I began to theorize the the issue may be in a very poor lid job on my particular chip by intel.

I delidded the chip at that point. I used MX4 between the block and the IHS and I used IC7(yeah I know) between the die and the IHS. I immediately noted a 10 degree drop in temps. I saw temps go down from 78 to 68 on the hottest core.

I was actually happy with this result, but I knew I needed to replace the IC7 with some CLP. I just didn't know how much of a difference this would make.

Well, it was VERY significant. Once the CLP was added, IC7 removed, I noted a further 10 degree drop in max core temps, even when I bumped up to 4.5 on the same voltage(there was no temp difference as long as I didn't change voltage, that I noted). 22.22 degree ambient temps. Running Prime95 in blend, and 16gb of ram @ 2400mhz. I am very satisfied with this cooler.

Here is a screen of the test yielding the final temps.

To recap:

h212 + push pull = 83 max, h110 vanialla = 78 max, h110 augmented = 77-78max, h110 delidded w MX4/IC7 = 68 max, h110 delidded, augmented, MX4/CLP = 57c max temps @ 1.256voltage(running either 4.2 or 4.5ghz),
