i5 4690k, H80i gt high temps prime 95?

kol12 · Apr 5, 2015

This is a new system. Running small FFt's I'm getting about 85 degrees. Is that too high?

4690k is running at stock 3.5ghz.

yes. that is quite high. an Overclocked i7 got only 73 C. check the thermal paste. [edit : check if the fans are plugged in too]

Check pump is running at max

kol12 · Apr 15, 2015

Thanks Martin. Funny you should say that as I have another issue that seem's related. I've noticed after running a game and then checking HW Monitor afterwards the max temps are quite high 68 degrees highest core. What I also noticed was the cpu fan had only gone from 820 rpm to 999 rpm. Doe's that seem like low fan speed for cpu load? I assume the cpu fan in HW Monitor would be the H80i GT fan? What are the max rpm on these?

Where do I check pump speed? Corsair Link? Because that's another problem I seem to have, the H80i Gt cooler pump and cooler fan are blinking red in Corsair link and have no values. The H80i GT Cooler temp has a value but is also blinking red.

Which version of Prime95 are you running? Later than 26.6 tends to excessively overheat Intel chips in a way that isn't representative of real-world use.

Prime95 Small FFT's is the standard for CPU thermal testing, because it's a steady-state 100% workload. This is the test that Real Temp uses to test sensors. The link above is to version 26.6, which is well suited to all Core i and Core 2 variants.

Core i 2nd, 3rd and 4th Generation CPU's have AVX (Advanced Vector Extension) instruction sets. Recent versions of Prime95 run AVX code on the Floating Point Unit (FPU) math coprocessor, which produces unrealistically high temperatures. The FPU test in the software utility AIDA64 shows the same results.

It's not necessary to run AVX code for thermal testing. Prime95 v26.6 produces temperatures on 3rd and 4th Generation processors more consistent with 2nd Generation, which also have AVX instructions, but do not suffer from thermal extremes due to having a soldered Integrated Heat Spreader and a 35% larger Die.

Thanks, looks like I'm running the higher version. I'll download 26.6

The pump should be connected to cha fan pin and make sure it's maxed out in bios

burbee · Apr 18, 2015

I just installed the GT h80i and have high idle temps around 40C

I got it to replace my 212 evo man im so disappointed whats wrong :/

burbee :

you applied the proper amount of thermal paste and made sure to give even pressure when applying the cooler to spread it?

burbee · Apr 18, 2015

aquaprofile :

The thermal paste was preapplied on the pump so i didnt feel the need to apply more..?

aquaprofile · Apr 18, 2015

burbee :

Ah ok. What I would do to test your temps is power off for 10-15 minutes and then Boot into bios for temps, not after a stress test because your CPU could still stay hot for a bit. My CPU stays at like 42c after im done gaming for a while but it actually idles at like 33 with an h80i

I didnt do anything to reach those temps. I didnt even stress test because as soon as i booted it for the first time the idle temps were already high ... Corsair LINK doesnt detect my pumps either and i think the fans are spinning a low RPM because of that

Is the pump properly plugged in to everything? Via a USB header block thing and Via fan header on the Mobor? Make sure its also plugged in to a Molex Power connection as well to pump!

aquaprofile · Apr 18, 2015

Has to be plugged into Molex Power to pump water, fan header to dissipate heat and then the usb header thing for LINK

burbee · Apr 18, 2015

aquaprofile :

I didnt see a molex connector thing coming out of the pump. Im using the new H80i GT guys

aquaprofile · Apr 18, 2015

burbee :

Ohhh GT... I use an h80i..

burbee · Apr 18, 2015

aquaprofile :

Yeah and the fans stay at 800rpm.. Corsair Link doesnt detect the pump and fans.

Do you have the mini Usb from the block plugged into the mobo's usb header?

Yes I have and I also tried switching from usb header.

kol12 · Apr 18, 2015

Sounds a lot like my problem..

kol12 · Apr 18, 2015

Well I reinstalled Corsair Link and now my H80i GT pump is showing but not H80i Fans.

kol12 · Apr 18, 2015

Well I'm getting somewhere with this whole situation please check my other thread and my most recent posts.
