CPU temp constantly at 89 degrees

Hi there, I've just built a new computer with the following parts:

It was all going fine until booting it up where the BIOS ALWAYS reads 89 degrees, regardless of before or after I installed my water cooler. This means that, despite changing the boot sequence, I can't go straight to Windows and must go through the BIOS as it thinks my CPU is 89 degrees so assumes there's a problem. (The fans are also spinning super fast but I think I can adjust that regardless). I've run RealTempGT on it and that says my CPU is 20 degrees but I know it isn't the most accurate of things. I was wondering if this is a motherboard issue and I should return it or if there's something which could be done about it? Thank you.

regardless of before or after I installed my water cooler.

Please tell me you didn't run your computer without cooling. That is very, very bad for a processor.

If you did have a different cooler, then I suspect that somewhere in the following steps you made a mistake.

1. You failed to remove old(er) thermal paste properly
2. You applied thermal paste incorrectly
3. you mounted the cooler incorrectly.
4. Your cooler is defective.

I only ran it for the test build and noticed it was 89 degrees - only for a very short period of time. If the thermal paste was applied incorrectly or the cooler mounted incorrectly wouldn't the temperature atleast fluctuate? It is literally always 89 degrees

You cannot, not ever, not for more than 3 seconds, if even that much, run a processor without cooling. You may have fatally ruined something in your processor.

use this and check cpu temp if it read same as bios you could have defective board sensor http://www.hwinfo.com/download.php

I've run this program and it says that the following message: https://gyazo.com/af2145d03dc5cfc3049e836e899afbb2
and but that is it. In the end part it also says all cores of the CPU are at a constant 89 degrees - no fluctuation at all in multiple tests on the motherboard section. In the actual CPU temp section it says its 20 degrees. This is shown in this screenshot: https://gyazo.com/0e6fcd817e6d21f6b33c63c1e463640d and https://gyazo.com/0e6fcd817e6d21f6b33c63c1e463640d

Well, unless you live somewhere where room temperatures are 15C - like in a very cold place, outside, with no heating, then even the 20C is an obvoisly incorrect temperature. No processor can operate without heating itself above the ambient or environmental (room) temperature.

It is my strong suspicion that you damaged the processor when running it without a cooler during installation.

Try this and see if it provides any meaningful output: https://downloadcenter.intel.com/download/19792/Intel-Processor-Diagnostic-Tool

like as suggested the cpu got off you could try to rma motherboard for a defective sensor and try the same with cpu .
