Hi all,

Recently I've been having some really weird temperature issues with m i7 4790k. It all started when I began playing assassin's creed origins which absolutely batters the chip. Long story short the CPU would go close to 100C and start throttle. Before I go on my rig is:

Gigabyte Z97 Gaming 3
16GB of corsair dominator 2133mhz
1080ti asus strix oc
i7-4790k initially keeping at 4.5ghz but recently had to lower to 4.4 ghz due to temps
H110i GT corsair AIO

I decided to delid my CPU. Went through the process to add liquid metal carefully etc. Saw some improvement in idle but on load it would still skyrocket in temps. Mind you i made sure always that I had tightened well the cooler and that it made good contact.

I was desperate as I saw the temps would get to 100C even with all default settings. After some testing I realised my H110i GT pump was faulty, as the temps in the block would go beyond 60c. RMA'd the AIO and just got a new one yesterday. Luckily this one works.

Installed it using arctic silver to cover with a thin layer the CPU and an even thinner layer on the AIO.
At 4.4ghz with 1.21vcore, 1.9VRIN and 1.15 CPU RING voltages I get about 45C Idle (32C on the waterblock) and 90-95C when gaming assassin's creed origins (36C on waterblock).

I don't know what else to try. This is the weirdest chip i've ever had in my life. I want to get some life out of it but these kind of temps look really non sustainable.

Is the chip just borked?
Have I done something wrong?
Is there a chance I didn't delid properly?
Do I need to put even less thermal paste maybe?
Is the AIO just not good enough for haswell devil's canyon?

Please any answers that might help would be extremely appreciated

maybe bad contact liquid metal and ihs try reapplying it , or bad contact with cooler apart from that i'm not sure what it can be .

Also ur cooler is fine i use to cool mine with h80 before so its not the problem .

i definitely would look in to reapplying liquid and reseating and thermal paste before doing anything else

All right, i'll try to check liquid metal and maybe add a bit on the IHT side as well to ensure it's making contact...and then re-seating everything
 
I'm @ 4.5Ghz at a slighly higher vcore on a Noctua NHU14S with no delidding and using Kryonaut paste. Temps never exceed 70 in game. I don't know what you rproblem would be.

I have it at 4ghz...won't it make it unstable if I put higher than that? How much should I increase you think?? And how much voltage is safe?

If you have a decent chip you ought to be able to get the Cores and cache at 1:1, though having the cache at 4.5Ghz wouldn't be too bad either. Information available from the mouth of intel via google. Google's blurb on overclocking voltage for about 7 years now has been "within 10%", so if you had a CPU with a default vcore of 1.0V, Intel would suggest that you not exceed 1.1V.... Can't say many people listen to that advice.

Seriously though, play with the cache (carefully). I used to get the occasional micro-stutter in BF1 on max everything @ 1440P (4790K @ 4.5, GTX 1080) and now with the cache at 4.5 I get no microstutters anymore. I'd go for 4.8 myself but money is iffy going forward for me and future CPU upgrades are a monetary mystery, so I'm being careful and babying this chip at a low voltage and low temperatures.
 
i think mine cache is at stock is there any comparison clocked cashe vs stock as it seems to be very minimal difference going by quick google search also there not much info about it
 
Raised cache to 4.2 and only got it stable with cache voltage of 1.29. I'll stop there caused it starts to heat too much and i don't want to raise anymore. 4.8ghz with 4.2 cache and 1080ti...should last without probs another couple of years! I'm happy! Finally getting performance out of this chip. May the delid gods be praised
 
I'm going to say the H100i is duff. I had the same issue running my 4790k @ 4.5ghz and then got rid of it. Now running an air cooler and temps are no higher than 65c at 4.5ghz

For 4.5 i only need 1.2 v and temps don't exceed 70c. For 4.8 i need 1.3 which is quite steep for has

Yep, not very simple to setup but once it's done.. The result is much better than switch! Uncapped framerate, 4k res and other graphical enhancements through graphics packs. Also..can play it with dualshock 4!

Cheers. Does it need a meaty GPU?
