4770k temps with h100i

[whitefox784]

I bought a 4770k and am cooling it with an h100i. I am getting temps in the mid 80s when running ibt maximum at stock speeds this seems really high to me and I really want to overclock but I don't see how I have any thermal headroom... Any suggestions would be appreciated.

Many possibilities. Did you do a baseline run with the stock cooler? The cooling head may not be seated properly/too much/little paste. Water pump bad/not pumping or a really bad chip. Did you set the voltage real high? Start with stock voltage. You may have a really bad package meaning you will have to delid to give you great performance.

What SENSOR is reporting the CPU temperature?

Some are on the CPU, and some are on the motherboard.

CPUID HD Monitor:
This should work fine and each core is under the heading "i7-4770K" so you should see changing values in the 30's likely when idle.

I did do a baseline with prime 95 with stock cooling and I was getting temps in the 90s so I stopped it because I didn't want to do damage to my CPU. That seemed really high to me too so I thought either I didn't install the cooler right or I had a really bad chip or something.

I am using HWMonitor and it does say 4770k in the program. My idol temps are in the 20s normaly so I thought that was pretty good maybe I just have a really bad chip???

I think you have the problem where the glue holding the lid (heat spreader) is too thick holding the metal lid away from the die underneath. First, if you can, get a warranty exchange, though I don't think you can since it can run without errors at stock frequencies. I would recommend getting on YOUTUBE and watch several videos on delidding. If you become comfortable with that, I really think it will fix your problem. Don't know what else you can do. Please keep in mind I haven't done any delidding 😉 though I have viewed several videos so if my upcoming build runs hot I am prepared to delid.

Will have to try to delid then I have never heard of that till now so ill have to do some research and watch some videos like you said I don't think overclocking is worth wrecking my setup mainly because I'm only going to be gaming and I've heard that oc doesn't affect fps that much so I may just leave it for now.

That sounds extremely high for stock. IMO the cooler isnt mounted correctly. If i had to guess its too loose

Overclocking:
I personally gave up on overclocking. (i7-3770K and Asus Z77 Sabertooth)
I have the Noctua NH-D14 and ran my fans at 100% while attempting overclocking. I easily got 4.2GHz with no other settings changed. I tried 4.3GHz and it crashed so I read all the tutorials and went back and made many changes.

I then finally changed things so it was 4.5GHz (single core) or 4.4GHz with two or more cores and things were STABLE.

Check out this comparison when stressed with PRIME95 (max heat; all threads):

4.2GHz (only frequency changed):
68degC

4.4GHz (many BIOS changes for stability)
88degC

*So to go from 4.2GHz to 4.4GHz the temperature (and thus heat) goes up 20degC. Ouch! That's only a 5% increase and unlikely to have much impact in gaming.

Additionally, the extra heat output can affect the graphics card performance as newer cards can overclock if they don't get too hot. It's not as much an issue for water-cooling but the voltage regulators still put out heat so that will affect internal case temperature.

A lot of people have no clue how to overclock Haswell because you need to make more changes then the vcore and multi.

Op go into the bios

44x CPU multi
44x cache multi
1.25v CPU voltage
1.25v cache voltage
1.9v vrin or CPU input voltage

While I don't have Haswell, my main point in still relevant. I also did explain you needed an overclocking guide. Overclocking the CPU by only 5% above 4.2GHz can have a HUGE increase on the temperature which makes me consider whether it's even worth it. Since that extra heat can also limit performance of a card like the GTX770 (temperature based overclock throttling) you can actually get a WORSE performance in games since overclocking the CPU may or may not provide any benefit but throttling the GPU definitely will lower performance.

I'm not saying don't overclock, but consider the BIG PICTURE. I'm also unsure of whether Haswell will consume less heat (I'm not talking about Temperature which can be a bit different) when overclocking.

Other:
As a side note, my experience indicates the following games currently have issue with HYPERTHREADING which causes stuttering:
- Assassin's Creed (Brotherhood for sure. A weird stutter.)
- Witcher #1 (severe stutter)
- Prototype 1 (has four issues actually which can all be fixed but that's off topic).
- Spider-Man Web of Shadows (unplayable with HT on i7-860 but very oddly my i7-3770K with HT has no effect. Perhaps a Windows thread management fix?)

DISABLING HYPERTHREADING solves the issues with the above games.

It seems you had a really terrible 3770K. Mine did 4.6 on air with a phlanteks. After delidding I could easily do 4.8 but it was a voltage hog

"It seems you had a really terrible 3770K. Mine did 4.6 on air with a phlanteks. After delidding I could easily do 4.8 but it was a voltage hog "

Not sure if my 3770K is "terrible" or not. When stressed so all eight threads (4C/8T) hit 100% at 4.2GHz (max heat mode in Prime 95) I hit 68degC in a room that's 25degC. Seems fine to me.

It's all the changes I have to make so it stays stable that basically remove much of the power savings modes designed by Intel that drive up the temperature. If it really mattered I could investigate further but in reality I have more important things to do; also I'd much rather have my room COOLER than gain a small performance boost which in practice doesn't really benefit me in gaming.

I bought a 4770k and am cooling it with an h100i. I am getting temps in the mid 80s when running ibt maximum at stock speeds this seems really high to me and I really want to overclock but I don't see how I have any thermal headroom... Any suggestions would be appreciated.

I have the 4770k, and H100i as well. I am currently running Prime95 CPU at 8 hours now. TEMPS are as follows:
Core 0 60C
Core 1 61C
Core 2 61C
Core 3 55C
H100i Temp 34.5C

I have the CPU OCed to 4100 MHZ using EasyTune. (I am clueless to Manual OverClocking as this was my first build, so to play it safe I just selected the "Light" overclocking preset.

Case used is a Corsair C70 case with one extra fan installed in the bottom of the case next to the Power Supply, and I replaced the stock Rad fans with Corsair SP silents.

Judging by the difference in our numbers I would say either there is something wrong with your H100i, 4770, or something else, like others have said too much/little paste ect.

Hope this helps.

I have jumped from fx8350 sabertooth today to 4770k sabertooth z87
Same issues here very high temp on stock clock and voltages
Changed paste 3 times 😉 was worry it's problem
Assembled h100i with push pull
I'm new to Intel my last intel had 133MHZ overclocked to 188Mhz 😉 wow that was speed 😉
Since that all the time AMD till today and little disappointment caused by temperatures
idle temp
40 36 37 35
load prime95
78 75 74 69

ambient temp 20C

What i discovered my temp of cooling water change only by 1C when on load
When i switch off prime95 temps just drop in 1sec from 80 to 40 Strange

If it's what intel want from me void warranty by some deliding then i think about RMA

Purchased a h100i refurb from frys for $70. It was refurb from the company and was packed/looked like new. this was installed on a 4670k which is set in an Asus z87-deluxe with 4 way optimization (1 click overclocking). (ps, stock h100i fans have been replaced with noctua nf-f12 fans)

4wo (4 way opt) takes my CPU to 4.5ghz with this cooler, but does not keep it there when i am transcoding mkv files to blu ray using MultiAVCHD, i end up getting a blue screen.

i dropped it down to 4.1ghz and i am running fine, i might be able to get 4.2-4.4, but dont want to waste hours transcoding to find out it will blue screen half way through.

my main issue with this setup, the corsair link software. you can set custom curves for your fans to rev up to X speed at X temp. BUT, the software only lets you use the h100i temp, NOT the cpu temp.

this is the issue, the h100i temp might go up 5 degrees when your cpu temp will jump from 32-65 degrees. it took me a while to figure this out, and i had to set my fan curve accordingly. at first i had my fan speeds go up at 30,35,40,45,50 degrees (based on h100i temp), but the h100i never reached those temps. now my corsair link settings are more like 30,31,32,33,34. corsair link also offers NO adjustment on the pump speed, it is always on 1 setting.

4wo lets you set fans to cpu temp, i wish corsair link did too. though, i did read in multiple forums that the temp of your cpu is minimally effected by the speed of your fans on the radiator. so having them on slow to max might drop it a couple degrees.

i guess i wish there was a better way to integrate Asus 4wo to work with the h100i. What are your guys h100i settings in corsair link, maybe mine or not the optimum?

Currently i have been transcoding movies for a couple hours @4.1ghz:
CPU temp: ~60
h100itemp: ~30
h100i fan speed: max, about 1,400rpm each (manually set to performance mode in corsair link 2)
cpu cache ratio: 38x (not sure what that is or means) (in asus 4wo)
cpu voltage: set to adaptive - currently 1.275 (in asus 4wo)

I know this thread is quite old, but here are my 2c.

In Haswell, you HAVE to make sure to set voltage (i'd do both core and uncore/cache) to manual override rather than adaptive. Adaptive CAN and WILL draw way more when certain instructions as requsted by the CPU which are specifically part of Prime95 and the intel brun test. Once you've found a stable configuration, you can set them back to adapative since no real-world use case will ever cause such a load.

I hope you figured stuff out...
