2600K @ 4,5GHz + H70 = 72°C?

post #1 of 24
Thread Starter 
Hello everyone,

I've been working on my new rig for a few weeks now, but I never get close to the temps of others using the Corsair H70...

I've used the autotune feature of my Maximus IV Extreme to get to 4.5GHz - going higher is causing my system to crash... running prime a few minutes, the CPU temp is going to ~72°C - much higher I've seen with other setups... I'm using pull/push intake and have 3x 230mm fans in my HAF932.

Idle temps are around 35°C - also very high I guess...

I'm not sure what I can do now - I already replaced the termal paste with arctic silver and switched the fans of the H70 from pushing out to intake (like its recommended)...

Are those high temps the reason I can't get past 4,5GHz via autotune? Has anyone an idea what I can do to get lower temps? How can I test if the H70/pump is working correctly?

Any help is much appreciated!

Well if your ambient temp is higher than the ones you are comparing it too they are never gonna be as good. Also add 2-3C on to any low temps you see as people have a habit of knocking a few degrees off for epeen. Also i would have thought using autotune will use a higher than necessary voltage maybe you can try lowering it.

I do not know much about the H-70 .I heard it definitely stomps the H-50 . I believe there is much better TIM than Arctic silver at this point ,and you can check on the many ways to apply the TIM . X shape ,Pea dot in the middle ,3 stripes ,ect. I'm sure someone with much more experience than me will help you straighten this out. I have bought from Frozen CPU and Newegg .If I owned a 2600K ,I would not spare a nickle to use the sickest TIM available. You are Lucky to have that CPU !!!!

I believe that if the pump is broken then your temps would be much, much higher.

Are you sure it's mounted right, and with the proper amount of paste? It's worth mentioning that some H70 owners put very high speed fans on, which might explain some of the temp difference from stock fans.

Try reseating with a different TIM. What are your ambient temps? Also what voltage are you set at to get 4.6ghz?

I would agree those numbers are probably too high by as much as 10 degrees. My set-up with a zalman air cooler doesnt get higher than mid-60's on prime95 at 4.6ghz, I would imagine an H70 should be able to do much better than that.

seems pretty normal for an h70

you cant really compare with other people that have a 2600k + h70 as there are too many variables such as vcore, ambient temp, case airflow, TIM/mounting, etc

make sure your pump is plugged in the right place.. needs to be running 100%

What is your ambient temp?

How did you power the pump? Through a header on the motherboard? If so... Run HWiNFO32 & look at the RPM for your pump. It should be at ~1400RPM. If you powered the pump directly via 4-pin molex then it's already 100% at ~1400RPM.

What's your voltage under load? If I remember correctly I was stable at 4.5-4.6Ghz around 1.3-1.31V and the temps were ~70C under load with prime95. Currently at 4.8GHz and 1.375V for 80C load temps during prime.

Forget autotune and overclock manually. It's really as simple as upping the voltage and changing the multiplier for the most part.

H70 isn't amazing, but at 4.5GHz I'd say 72C is definitely hot ESPECIALLY with a HAF! Don't mean to be a fanboy here (first thing you'll do is look at my sig and see I own a 212+) but I feel the H50/H70 are bested by air coolers like the 212+/Noctua. I've built (I sell all sorts of custom builds) more than a couple H50 setups and the H70 isn't much better. You should be at around 60C at most. It COULD be bad sensors, though that's unlikely.

The obvious:

Try different paste
Try different paste method
Ensure mounting is correct

I have an H50 with a i5 760 at 4.1, HAF 922, pretty much same fan set up, and my temps are lower than his. Sure his clock is 400mhz higher, but these chips are supposed to do that easily. Try Reseating, maybe invest in new fans for the push pull config?
