I've provided a link to a photo of a screenshot I took maybe 2 minutes after starting Prime 95.

Why is there such a huge discrepancy between readouts? HW Monitor reads almost 60c at idle on a STOCK i7-5820K with H105 water cooling and Tuniq TX-4 paste.

What is going on here?

That happens sometimes with monitoring programs. Try using HWinfo for temps and see what it reads.

I would trust the core temp program. Sometimes the issue could be what sensor they are taking the temperature reading from.

Here is the stock settings read by both HWinfo and CoreTemp... 60c and up for stock settings? Doesn't that seem way high for anyone else? I've been reading up on overclocks on this chip and lots of people are in the 40c range with a 1.0GHz overclock and about .3V increase... doesn't seem possible!

Here's an overclock setup. Temps over 85c!? I don't understand...


Try using OCCT Linkpack or AIDA64. Prime is very hard on Haswell CPU's.

Of those three, which would you recommend? I've used occt in the past...

I would use OCCT. I've found stability issues with my OC using Linkpack in ten minutes, where as with AIDA64 I could go hours and hours without a problem. OCCT definitely has the better program to check stability. You can also set temp limits with it, which is a nice feature.

I'm gonna try that, then. Thanks for the recommendation.

Just to play devil's advocate here... Isn't it kind of a good thing that Prime is hard on Haswell? Doesn't that give you a real true stress test as opposed to a lighter, easier stress that may not show true numbers and effects of CPU load?

It's good, yes, but only to a point. I've seen some report that it seriously jacks up the voltage, which you definitely don't want.

I also don't like the really high temps. Even with good cooling, Prime makes these chips run really hot. Plus, it didn't help me find my stability issues. I ran it for an hour and it was fine, but it was the same as with AIDA64. I could run OCCT and it crashed in a few minutes (usually around ten minutes in).

Set your voltages in bios, don't let software set the voltages ever.

I wouldn't dare let software set my overclock. Here's a readout after a few minutes with OCCT. They look a lot better, but still kinda high for having quality thermal + water block cooling...

Those temps look pretty good. Core #2 and #4 are a bit high, but that may just be because of temp spikes.
