My cooler is a Noctua NH D15. My case is a Fractal Define R5, one exhaust fan, two intake 140mm fans.

OpenHardware Monitor shows 6 temps, one idling at ~102 C.
RealTemp has 4 temps, idling around 35 C.

Screenshot showing both side by side: http://imgur.com/mnZQCXT

Is open hardware monitor being faulty or is there a core at 101 C right now? Do I need to remove my heatsink, replace the paste, and try again? Kind of nervous about this.

In fairness, my computer is on a tiled floor close to a door, and it's cold outside !
I still think your temps are good (and yes, Prime is a bit insane) but reapplying paste wouldn't hurt, other than you say it's tricky. I would clean off old paste and put a very thin layer on the face of the heatsink, not the CPU, as this guarantees you have covered only the working area of the heatsink. Get the screws all just started as evenly as you can, then alternately tighten them a half turn or so each, and be sure to not do one side at a time.. Alternate like you would tighten a tire... start top left corner, then bottom right corner, then top right, then bottom left...rinse repeat

I believe OpenHardware is lieing. There is no way one core can be so far off the others without bringing their temperatures up. Also, at 100 degrees, the CPU would shut down as that is its max. You can try other popular temp software to confirm this, but it looks like RealTemp already knows the truth.

I was told to do the pea method, but the Noctua NH D15 cooler doesn't allow you to force it down evenly on the heatsink. You have to line up two spring coiled screws, and when you do the cooler doesn't make contact. Only after you screw it in does it make contact, meaning you can't apply even pressure when merging it to the thermal paste resting on the CPU. Should I just cover the CPU completely myself instead of doing the pea method?

Also what do I use to remove the thermal paste, will Isopropyl alcohol work?

It still makes me nervous to see that temperature. OHM never showed me temps like that on my i5 2500k. Is there another software you could recommend, and do you think I should re-apply the paste to be safe anyway? The pea method doesn't seem to make sense for the noctua cooler since even pressure can't be applied when installing it, so should I try spreading a thin layer over my entire CPU surface?

You can see in the OpenHardware that your max core temp was 65.5.. nowhere near the 100 degrees.
I use HWinfo, but HWMonitor is also popular.
You could re-apply paste (isopropyl alcohol is fine to clean off old), but I'd verify temps with other software first... your idle and max temps are otherwise suggesting you did it fine.

Temperature #4 on my screenshot shows 102 degree C max. What should my average idle temp, and my average max temp under load be? I tried googling "i7 7700k idle temperatures" and can't find any official results, just results about people on forums making threads to ask why their temps are so high but no numbers for what the temps should actually be. I thought the cooler I got was supposed to be pretty high end but it seems to not be performing any better than the 212 evo I used to have. Do they all tend to perform the same at idle? I haven't monitored temps under load yet.

I'm idling about 5 C higher than you are. I ran P95 for the past 15 min and this is what my temps look like. It reached a max of 79 C. Do you think these temps warrant a thermal paste re-application? Searching google seems like for p95 those temps might be normal, but for idle I'm idling higher than I should be.

Perfectly fine for a bench result. You'll not hit that load during normal use.

Make sure you have the latest version of the monitoring software available. New chipsets and CPUs always have some issues. If you are getting erroneous results help out by sending your system info to the developer's of those tools.

You have nothing to worry about, those temps are perfectly normal. The core temp is the one you should be looking at, there's no way one of your cores could be operating at that temperature, Intel chips will either throttle down or shut down your computer if you get near that temperature. HW Monitor was most likely glitching, those temps are fine.
