Cpu temps are high stress testing. Help!

[Joshua99]

Hello , I have recently completed my build for my pc. I was considering OC'ing the Cpu but my stress tests are running around 95-99 c at 100% loads when cpu is stock. Is there anyone who can possibly give me some insight. I've read through a few other peoples issues and watched some videos on how to get your pcs running as cool as possible.

My build :
Power supply is Silverstone st85F-P 850W ATX plus silver certified
Case is Thermaltake Overseer RX-I Snow Edition
Motherboard MSI Z87-G45 Gaming LGA 1150 Intel
Cpu Intel Core I7-4770K haswell 3.5GHz LGA 1150 84W
Aftermarket CPU COOLER is the Corsair h100i
GPU is MSI GeForce GTX 780 3GB 384-bit OC EDITION
Ram ADATA XPG V2 16GB 2X GB 240-PIN DDR3 2400 (PC3 19200)
And I got windows 8.1 on a 128gb ssd and a 1TB secondary HD

I have purchased 3 additional fans thinking airflow would fix my temps.
I purchased a better 200mm fan which I placed on the front of my case and put the 200mm fan on my side panel as an exhaust since my GPUs fans push air down I figured exhausting it would be best for heat. I replaced the exhaust on the back of my case because the stock fans are kinda weak the new fan shoots air out like a champ I picked up the Cooler master sickle flow 120mm 2000rpm . Although I have added fans to increase airflow attempting to get as much air through and out in the correct directions and having the h100i my cpu temps seem high. Stress testing only for at most 10 minutes before temps on my first core are hitting 99c. Idle temps are roughly 26-32c and if Im running games it will pick up from 35 to 60 depending on the game. (only game so far that put its around the 60-70 degrees is watch dogs on nvidias recommended settings which is basically ultra with anti-aliasing and a few others graphical settings modified.) From what I read online pcs with this aftermarket cooler should run around 70c on a full load and OC'd. Is there anyone who can recommend what I should do , and if you need anything else let me know . Also I use CoreTemp to watch temps. prime95 for stress testing.

Have you applied thermal paste correctly? And is the CPU overclocked?

 

[Joshua99]

Cpu is stock not OC , and the h100i comes with pre-installed thermal paste and from what I read online its alot better than pastes most people purchase.

 

[Georgehillier]

Is the watercooler definitely put on properly? It may be worth cleaning off the thermal paste and re applying it. What are your temps when idle?

 

[Joshua99]

The information you've asked is all in my original post lol. My temps are 27-32c idle. Which seems normal. The h100i Is installed correctly I watched many videos on it to ensure I have not only the fans pushing the correct way but hooked up to the cpu correctly. The thermal paste comes pre-applied with these coolers and from what i read its best not to take it off and apply a different paste.

For anyone who helps me out I will attempt to respond as quickly as possible =) any help much appreciated.

Sorry, it was just such a big paragraph and couldn't find it while skim reading

If it's not overclocked and it's applied correctly then I don't know what else it could be. Before you had the H100i what were the temps like? Or did you build it with the H100i originally?

 

[Joshua99]

Built it with the h100i

You should also ensure that the H100i is mounted with the fans facing the right way. You want the fans to suck in cool air from outside the case, which will pass over the radiator and cool the liquid inside. If the fans are drawing the hot air out of the case, the water passing through the radiator will be heated.

my case , like many other cases push air from the front / bottom outwards to the back / top . I get that it may help to try to intake cold air from the top but that would defy the current cases airflow. Ive watched many builds with the h100i which have the fans set from inside the case shooting through the radiator as an exhaust and they are running temps around 60c fully loaded.

As directed also from corsairs main site http://www.corsair.com/en-us/blog/2013/february/how-to-install-the-hydro-series-h100i-cpu-cooler the default set-up has them as exhausts. I don't believe that this would be causing it to run 95/100c fully loaded. I may attempt to reinstall a brand new h100i... I will wait a little maybe someone has delt with this simular situation. My case now currently has 7 fans running through it lol...

1x 200mm intake in front.
1x 140mm intake bottom
1x 200mm intake side (tried as exhaust also to exhaust gpu cooler no change in temps)
2x 140mm exhausts through cpu cooler
1x 200mm exhaust top
1x 140mm exhaust back

One thing I've noticed from the previous screenshots is that the CPU voltage is at 1.32V at 100% load, which seems excessively high for a Haswell processor. Granted, automatic voltage always allocates too much, which in turn increases the temperature, but a stock speed Haswell i7 at 1.32V doesn't seem right to me. At that voltage, you should be getting around 4.4Ghz.

If you haven't already, manually reduce the CPU voltage, which will help bring the temperature down. Start at 1.2V and increase or decrease accordingly.
