CPU running too hot with water cooling without OC (Haswell)

xboost · Jan 12, 2014

Its been about a week since i built my pc, and today i decided to run prime 95. I have Corsair H100i with better fans. I am coming from an sandy bridge i7 which run on ok temps. But my current haswell cpu (4770k) without any OC runs too hot. I saw 99 C on hwinfo and Coretemp in a few mins after test starts. Then immediately stopped the test, i dont want to pass 100C (TJ max). Should i remove IHS and change thermal paste since they used cheap thermal paste instead of solder? While gaming i saw 89 C without any OC too and i want to be able to OC.

Don't de-lid it. Sounds like you have a bad cooler or a bad application of thermal paste on your cooler.

change the termal paste and make sure its correctlu applied and the IHS is making proper contact and that the collinging liuquid is flowing right and you are not being cheap and using water

I am using corsair H100i with thermalpaste that came with it. Should be fine.

Unless you reused it or something. Did you take the cooler off and not reapply it?

Is your pump ok and is the temp in C or F? Please look in the bios bcoz hwmonitor sometimes gives false readings.

rounakr94 :

Pump is ok bios says same, mostly Temp is in C as i said

Did you remove the plastic film from the Copper contacts?

xboost · Jan 12, 2014

rounakr94 :

Yes

ewok93 · Jan 12, 2014

Uhm... Did you plug it in? I have to ask.

xboost · Jan 12, 2014

ewok93 :

Of course

rounakr94 · Jan 12, 2014

Get a better thermal paste "arctic silver 5" but use a pea drop amount and give your fans a push pull config.

xboost · Jan 12, 2014

rounakr94 :

I will probably get thermaltake TG3 Extreme if it continues like this, there isn't any arctic silver in my country. My fans are already on push pull

BTW 100F = 38C which is normal. Are your sure that its Celcius? Plz post a hwmonitor screenshot.

ewok93 · Jan 12, 2014

Yeah, it sounds like Fahrenheit, those are the exact temps I'd expect with that cooler and chip.

xboost · Jan 12, 2014

No it is celcius

rounakr94 · Jan 12, 2014

Then the only thing coming to my mind is a faulty Pump or Incorrect Installation. Please triple check everything and report back.

Most likely your problem is in core voltage, try the flowing:
1- Uninstall any over clocking programs you have then go to the bios.
1- DO NOT leave core voltages on auto or on adaptive mode, only in manual if you are going to do any kind of stress test.
2- Start with every thing on default in bios then change core voltages to manual I would start with 1.00v for the stock speed of the i7 4770k then save and boot if you get any errors then add very tiny bit of voltage make it 1.01V if not then 1.02V ( REMEMBER make your increments in 0.02v or 0.01v only and NOT more) until windows boots without errors, then watch the temps and you will wonder!
3- If you start any stability testes and get any errors then add a tiny bit of a voltages again (+0.01v only) and test again until you get stability results with reasonable temps.
4- I would suggest you leave everything else on bios on defaults except Vcore on manual.
