3770K + Maximus V Formula + H100i Overheat

[anupom]

Hello guys,
My CPU is 3770k with Maximus V Formula. I bought "Corsair H100i" but its giving 45-60 C at idle, and 100+ C at 100% load @ stock speed. ambient temp. is 32c. is that normal?
Someone just said its my cpu problem. because i'm having 45-60 C with stock cpu cooler as well as h100i @ stock speed!! Please Help!! What is the problem why is this happening? Others who are using same cpu with air-cooler getting 60-70c on load. 😕

Note:My RAM is corsair running @ 1600MHz with XMP profile
When i run @ 1333Mhz i got some change in idle(pic) but No Change in Load Temp.
If i mount h100i differently on cpu temp changes little bit but not even close to normal!!

Tried things: Changing H100i, tried BIOS default Setting(ver. 1903), Installing Fresh Windows 8.1, Tried different Thermal Paste, tried changing airflow direction...!!

Used Software: RealTemp, CoreTemp, HWMonitor, Prime95 For Test...

Hare are some screenshots(ram without xmp @ 1333mhz):

I've not OC my CPU. I'm not too experienced in OC. Need Help Guys...!! Why my CPU overheating...How may i solve this...
thanks for your time.

Yes, this is too high. Make sure that the H100i is hooked up correctly according to the instructions so that the pump has power. If it's not working then exchange the H100.

i already tried exchanging it and also checked on another pc. cooler is not faulty.

is the temperature ramping up to that? does the system shut down after a period when idle?

or is it instantly hitting those temps?

If it gradually builds up then definitely look in to your H100i, I use one of these with my secondary system and have tested it on my i7-3770K. The temperatures are far lower than you are experiencing. I would expect the system to shut itself down, even when idle, if the H100i wasn't moving the heat away though as Ivybridge cook pretty hot.

Can you also go in to your BIOS and monitor the VCore read outs. I use the 3770K and under BIOS, if set to Auto VCore, it should register around about 1.045V

If it's higher than this then set VCore to manual and adjust to 1.100V, also check your VCore in windows by downloading CPU-Z and running it, it will show your cpu voltage more accurately than HWMonitor.


EDIT: Looking at your temperatures on HWMonitor, I would stop using Prime95 or other CPU intense software until you get those idle temperatures down. 3770K's TjMax is 105C, which you're hitting a lot under load, so you're going to end up killing it.

bro, its instantly hitting those temps. are cpu voltage and vcore voltage same thing? i changed it auto to 1.100v. Cpu-z showing "core voltage: 1.104v" but HWmonitor Showing "VID: 1.251v" and BTW i'm getting hottest core 82c (large FTP test p95) @ 3.9ghz with ram 1600mhz xmp.
waiting for your response.... thanks

Yes, 1.104 is the same. There will be a small amount of drift and also possible variation in the accuracy of the reading but that is pretty darn close. The vcore is the important one. The VID is not the actual supplied voltage, hence wouldn't generate heat.

82c does not seem bad for p95. Perhaps you have a bad CPU temp sensor and it's not actually that hot. You would need an external temp sensor to check it though.

Bro, if 82c @ 3.9ghz not bad then how can i oc my pc? bad temp sensor? how can i get external temp sensor and check?

Sorry for the delay, was going to post a reply but the forum was down and then I was AFK a few days.

I don't know what is available in your region but a fan controller with temp sensors like the NZXT Sentry-2 would work.

I meant that you are running a very stressful load that you would never see except for a synthetic test and the highest core temp you are seeing is within Intel spec. That is considered acceptable even if not ideal or desirable. Every chip is different. You may not be able to OC this chip very much at all.

Sounds like you got things sorted with a repaste though. That's still hot but as long as you aren't going above 90c with Prime then you should be much lower with gaming type tasks.

Those temps do seem a bit high. does your pump seem noisy. What is the position of your rad are the lines at the top or at the bottom. The lines should be at the bottom so any air trapped in the rad will be at the top. In those closed loop systems its hard to determine the flow of coolant or even that there is any coolant at all.

hare are some photos of my cpu and mounting inside casing... airflow tried both. 😕
