Well I'm not sure what's going on, so I'm bringing this to the experts
I got a replacement 4770k after my unfortunate incident with the hammer (just to be clear, what happened was entirely my fault for using the rong tools and shouldn't dissuade anyone from trying to delid), and after I installed it with the stock Intel cooler at stock settings it reported 100C temp on all but one core (which seems to max out at 95C+-) when using IBT and Linx.
So I took it back to the store and they sent it to the lab. Today they brought it back to me saying that they tested with the stock cooler and maxed out at 82C with linpack.
I put it back and it still reports a temp of 100C for me, but after using IBT and Linx for the last hour I'm not sure what's going on.
Edit: also wanted to add that I'm getting around 45-50C at idle
The Linx on the left is without AVX and the one on the right is with AVX.
The Asus AI Suite 3 reports no more than 88-90 degrees, but from what I know their reading is an average of what the CPU reports and a thermal probe they placed underneath the socket.
RealTemp and HWMonitor report pretty much the same thing at around 100C for all cores.
I'm not sure, but I don't think the CPU is throttling, it seems to stay at 3.6-3.9Ghz on all cores during the tests. All the voltages seem in order and MB and VRM temps are in line.
When I put my hand over the CPU HSF I don't really get a blast of heat as I would expect when running these kinds of temps. I should also note that this is the same HSF I used on my previous 4770k at stock setting with the temps staying at under 80C, and I also used it on the Pentium I was using while waiting for the new CPU and it didn't go over 55C. I also tried to reseat the HSF multiple times and each time I took it off I saw the thermal paste (MX2) application was perfect.
This is getting long so I'll cut to the chase:
Is my CPU throttling according to the Linx/IBT results? Linx with no AVX gives me an average of of 51 GFlofs and Linx with AVX and IBT give an average of 82-83 GFlops. Are these the expected results at stock settings?
Is this temp reading simply false? Later I'm planning on taking the CPU to a friend to see if it gives the same readings on his MB. Maybe it's just giving me false readings on my MB (Maximus VI Formula).
Could the CPU actually be reaching these temps? Personally I would expect it to shut my PC down or something at these temps, or at least do some serious throttling.
Do you think delidding it would solve the issue? If it is a false reading my problem is that once it goes over 75C all my fans go to 100% speed, and I'm going to have 14 Corsair SP12 PWM high performance fans and a Swiftech MCP 35X2 off the CPU header, and I can't have them running at full blast whenever I put the least bit of stress on the PC.
If the temp reading is indeed false and only on my MB I might just sell it off and get a different one. Will probably lose some money in the process, but if there's no other choice...
