80/85 degrees on the stock cooler at stock clocks and voltages?

Something has to be wrong there surely.

The Intel cooler is awful but it's not that bad

I don't know, they seem to be running quite hot. Everything is on Auto so I guess that counts as stock, but it's basically running at 4.4Ghz and has the voltage bumped up. Will get a screenshot later of specifics.

The 80c is under full Cinebench load.
 
Guys never use your vcore set to auto. There has and always will be issues with auto vcore as the bios/board does a best guess attempt at what vcore you need and it always overvolts.

Go in to your vcore settings and set vcore to manual and set it to something like 1.25. Don't use offset as that rarely works properly either. Then just change your mutliplier. 1.25 should be good for 4.5ghz if you can get 4.6,4.7,4.8 stable you probably have a good chip.

You can leave enhanced c states on that is fine.

When the cores idle it will now push 1.25v through the CPU at all times but your CPU will down clock to 800mhz or so and will cool off down to about 30°c anyway.

Few people overclocks with vcore on auto and rarely do they get offsets working correctly that I have seen.

Most guides the first thing they tell you to do is set manual voltage.


Oh and one more thing I totally agree with 8Pack on is don't get hung up on your core temperatures when running synthetic benchmarks that artificially overload your CPU. Run the games you like to play and watch your temperatures then. Synthetic benchmarks put your CPU under completely none life temperature and load conditions you would normally never encounter.

Finally ordered my 4790k

After weeks of waiting I've finally got round to getting my 4790k ordered, will be arriving tomorrow and I can't wait to be able to use the Z97 Sabertooth mark 1 motherboard I bought for it.

What are your idle and load temps?
Click to expand...

72,75,76,68 on load, about 35-38 on idle. The last core is much cooler than the others for some reason.

Using a custom loop with 2 gtx 580's. Could probably get it a few degrees cooler if I increased the pump flow and cleaned the water block. Tubing leached and is clogging up the block.

Just got mine, L418C134. Hopefully be able to install in the morning. Never had Intel before should be fun.

Hi All

A virtually standard system

Intel Core i7-4790K
Asus Z87-Deluxe (Bios 2004 latest)
16 Gig G Skill DDR3 2400MHz (At 2133 9-11-11-31-Cr1 1.52v)
Gigabyte GeForce GTX 780Ti WindForce 3x OC
Prolimatech Megahalems Rev C CPU Cooler
IC Diamond 24-Carat Thermal Compound
Corsair Graphite 600 Case
Sound Blaster Z
Corsair 750W Power Supply

Batch L336D107

Ambient Temp 22 degrees C

Std settings with xmp (reduced mem to 2133 reduced timings to 9-11-11-31-Cr1 at 1.52v)
Using xmp fixed cpu cache at 1.192v.
Not using multicore enhancement in bios

All running well

My L3 is also very hot, just gave it a quick try with p95 ver 285, 4.7ghz oc and temps shot to 86-94-95-86, 1.2593v in bios, 1.264 @load. On default bios settings temps are pretty similair, i even manually lowered voltage to 1.200 and it was still in the 80's. Using benches like real bench, XTU etc gets to the 70's. Games in the low to mid 60's at 4.7.

From reading the owners thread on overclock.net, the L4's do seem to run cooler for the most part, and are generally clocking higher on lower voltage.
