Hey guys, over the last couple of weeks my computer has been freezing while I am in the middle of a working on some 3D prints (using preform) it has been getting increasingly worse, so I installed core temp yesterday and my intel core i7 doesn't look good :( (the only thing open at the moment is google chrome)

I've cleaned out my computer interior, blew out the dust, made sure all the fans are running ok and put it in the middle of the floor for ventilation. All drivers are updated as well. I don't know what else to do or check - please help!

Maybe you may need to check the thermal paste on your CPU or the fan to the CPU may not be working properly or clogged.

If you have computer knowledge it should be under the fan in the motherboard. You may need to check on youtube for instructions on how to check it out depending on your computer model or make.

You did not post your system specs so I have no idea what motherboard you are using. Most board mfg have purpose designed monitoring software to monitor temps/voltages. I would REALLY use that over a third party program. If you have a big box system ie dell, hp, whatever, use the intel extreme tuning utility;
https://www.intel.com/content/www/us/en/support/topics/utility-tools.html

You asked about thermal compound and how to replace. First of all, I always recommend pulling the motherboard out of the case for an intel type cooler. Once the board is out of the case, you release the four pushpins by turning in the direction of unlock. When all four are released, pull the cooler off and clean ALL parts with 99% or 91% alcohol. Apply new thermal compound IAW [in accordance with] the compound mfg's instructions. Reinstall the cooler and then reinstall the motherboard in the case.

Note R&R a cooler can be done in the case however [IMO] you are more likely to do the job correctly with the board outside of the case. With the board outside of the case, you can support the back of the motherboard while pushing the pushpins back into place AND you can inspect the back of the board to be sure all four are fully seated.

OK, it is overheating. Modern cpus will downclock or throttle attempting to keep temps within limits. You need to fix the overheating. If you are not comfortable working inside the case, then you are going to have to take the system to a shop and have them fix the problem.

If you want to attempt to fix this yourself, first open the case and check that the cpu fan is working, the heatsink is in fact firmly attached, all other fans are working, etc. If all looks ok, then you need to pull the heatsink fan OFF and either replace the thermal compound OR just replace the heatsink fan. The new one will come with a thermal pad so no need to apply compound. If you are going to reuse the old one, then you need thermal compound.

Note there are numerous videos available online showing how to accomplish this task.

Again if you have to R&R the heatsink fan, I recommend pulling the motherboard out of the case. While this is more work, you are less likely to break something and more likely to get the cooler installed correctly. The intel type coolers can be a pain for the inexperienced builder; the amd type coolers can be done in the case since those are just about idiot proof.

Just a few more thoughts;
1 Watch a few videos of installing an intel cooler
2 Be sure and clean all parts with 91 or 99% alcohol. Do not use the 60% stuff you find in the supermarket; it contains lanolin and will leave a residue
3 Once all four pushpins are released, give the cooler a gentle twist prior to pulling it off. If it will not come off easily, STOP do not force it off. Plug in the pw connectors from the pw supply [both atx and aux] short the pw switch pins on the motherboard. The board will now pw ON. Let it run for 1min and pw OFF. The cooler will now lift off easily
