Hey all

I'm putting together a new build, and was wondering what would you think my temps would be around? I know I can't get a 100% accurate answer, but any sort of guideline would be great

Here is the Build.

Intel Core i7-4770K 3.50GHz (Haswell) Socket LGA1150 Processor - Retail

Asus Z87 SABERTOOTH Intel Z87 (Socket 1150) DDR3 ATX Motherboard

Corsair Carbide 540 High Airflow ATX Cube Case - Black

Corsair Hydro H100i High Performance Liquid CPU Cooler

I've heard the haswell run very hot! and I am not very confident on the delid process

any help would be great.

Thanks
 
No overclock under regular load: 50c or under.

Overclock and load: 60-70.

Prime95 or stability testing with overclock: 80-90.

Totally depends on voltage and frequency + silicon lottery.

In any case, this setup is one of the best options you can get, and any of these temps are still safe. Very safe.
 
My 4770k in a HAFX cooled by a H100i does the following, prime stable....

4.4Ghz 1.150V 65°C
4.5Ghz 1.2V 70°C
4.6Ghz 1.272 78°C
4.7Ghz 1.332 90°C

I leave mine at 4.4Ghz for 24/7, in the recent BF4 beta it was sitting around 50% load at ~55°C. What you'll get from yours really depends how lucky you are in the silicon lottery... If you're feeling brave then a delid will help with temps, reports are of anything up to a 20° drop.
 
You'll still need to apply paste.

mine runs on a full load at 60c when the gfx cards are warm, idle is 30c

Do you need to apply any thermal paste with Haswell CPU's?

I think I read somewhere that this is no longer required now?

Yeah you do!

Haswell does not change the fact that the headspreader on top of the CPU is not flat. Neither is the base of a cooler. It would be impossible to make them 100% flat, so thermal paste helps that.

And better the paste, better the temps :)

Weird stuff you're reading.

I'm glad I asked the question then! Thanks Make!

Any recommendations on thermal paste to use?

Looks like I have to do more reading then...

Here Stulid tested the OCuk paste range :) The gelid test winner is great I heard.

If you are brave and are not using an aluminum heatsink, you could use the Coollaboratory Liquid metal stuff.. but it is not for beginners.

I just used the factory stuff on my H100i.
 
I'm planning on buying the Corsair H80i liquid cooling solution and looks like I will now be combining it with the Gelid TIM paste as suggested.

I thought I had pretty much nailed down everything for my upgrade, but it looks like I still have more stuff to read up on.

Thanks Make.

No problem. I think you can skip the paste, as according to tests the corsair stock stuff on these i models like H80i and H100i is very high quality "Dow corning" paste. It's easier to install with the stock stuff and you shouldn't see any difference. :)
 
Under p95 small fft, mine at 4.5ghz, (1.2625 in bios, 1.264 windows idle, 1.2800 load) hits the low - mid 90's. Mid 70's using prime blend, 65c in bf3. Cooler is an Alpenfohn k2 with x2 akasa piranha 120mm fans. Liquid ultra paste on the ihs.
 
Ha, I hope I win the lottery too.
Preferably Euromillions, but silicon will do :-)
Buying my 4770K tomorrow morning and setting up a custom loop.
 
I started using Intel Extreme Tuning Utility as that seems to be a bit more gentle on the temps for Haswell. Running OCCT the chip got 90 ++ hot running stress tests. With Intel im at 60 / 70 stressing and that seems to be more in line with what real life us would be.

Im running mine at 4.5 / 1.255 volts also ring is @ 4.3/1.9
Had problems in the beginning getting it stable at 4.5 before I lowered ring speed. Especially if I wanted to keep the voltages as low as possible.

How high do the temps go when using the Intel Extreme Tuning Utility. I remember getting crazy temperatures when i was using Prime95 too after overclocking my i7 920 CPU.

Im trying 4.6 at the moment and IET util is running the CPU at 70 degrees.
Had to bump my voltages up to 1.29 but I'm still not stable :/

Note all my gear is under water ;) The ones that produce heat anyways.

EDIT: Seems like I need 1.3V to get it stable over 10min of stress testing :/
Though my temps are still just below 70 :)

I have the Phobya UC-2 for the CPU (being cooled by 240 & 280 rads).
The 240 has 4xCorsair AF120 running push/pull configuration. The other has two NoiseBlocker (140) fans. They are connected to a fan controller with a water temp profile for controlling the fan speeds.

So seems I got through 1 hour of stress testing without windows going down on me :)

The temps are fine as long as I dont use OCCT, then it all goes to hell. Have gotten 100 a few times, and thats when I stopped using it.
