[SOLVED] CPU is overheating ?

[EvilDuckling]

Hello ,

I have been having overheating problems with my i5-14600KF, so I would like to ask if there is anything I can do to make the situation better temporarily (undervolting, etc.) and what cooling option should I use if mine isn't enough. If what I have is enough and my high temps are abnormal then I would like to know that as well.

I get 90-100 pretty quickly when I try to do a stress test; some of the cores seem to reach 100 while some stay around 83-85. Took the screenshot after i closed stress test , max values are pretty much what i get during stress test and current temps are no load temps. When i play for example starfield at maxed settings I get like some cores at 70 and some of them are at 84 , not bad as stress test but still very high temps.

I use Akasa Alucia H4 Plus and thermal paste came with it T5 Pro-Grade Plus. Also i wonder if i add one more fan to the cooler would it help ?

My case is cooler master haf 912 and i basically have cheap random fans at top and left side addition to stock ones.

Thanks in advance !

Not exactly a large air cooler. The review you posted shows a max dissipation of 200 ish watts. CPU should max out around 181W if the Intel standards are adhered to. So it hitting 90-100C is to be expected under those conditions.

Seems like it is working just fine for games though.

You can try your hand at undervolting of course. If you haven't already, you should download the latest BIOS for your motherboard to apply the Intel microcode fixes that take care of Intel's voltage spiking problem.

I don't have a 14600KF, but a 13600KF, I had it undervolted for a long time, after upgrading the bios with microcode 0x129 I canceled the undervoltage, set everything to Intel default and auto and temperatures remained OK. Do you have the latest bios?

I'm not sure if your micro is air cooled with a fan or water cooled. I do know that a thin evenly covered layer of thermal compound is better than a thick coat. I usually roll the paste on with a perfectly straight and well rounded and finely polished sled rod I took out of a cd player. I coat the processors heat sink and roll the grease around. It's ends up thin and well covered.

Then I inspect the heat sink that makes contact with the micro. If the heat sink appears tarnished from storage I buff if lightly with a bit of KROIL oil. This is special penetrating oil that softens oxidation then I use an eyeglass cleaner non abrasive cloth to wipe it clean and dry. Then I secure the heat sink to the micro as usual.

I use a three-fan water cooler and the micro temps rarely exceed 60c. However I won't do a stress test because heat destroys micro's if there is something wrong with the heat sinking. I keep an eye out when running a video game or other high micro usage and it's never exceeded 70c. It's an intel coffee lake 6 core that overclocks up to 4.7 gig dynamically when it needs to. Whatever, I serviced electronics for 45 years and heat kills.

Specs are one thing to meet but another to meet in the long run. I've heard tale of intel outlasting amd in general and it's debatable but I think you are asking for trouble at those temps. I would run it normally and watch the temps. If they temps continue to increase I'd double check your cooling system and if the problem persists with the cpu voltage the same; you might want to contact the manufacturer and tell them what's going on.

I have the i5-14600K version. It's running on an MSI Pro Z790-A WIFI MB. Luckily, there was an option for type of cooler when I first set it up on the first post. I chose the stock cooler and it set the bios settings low, so the CPU was never shocked at the highest performance level. I have gone in and goosed it to the tower cooler setting and then a little deeper on that setting with the voltages. I used the Thermalright Phantom Spirit 120 SE cooler. Excellent.

There are a couple videos you should watch. Here are the links. They were generously shared with me. It's a great explanation of the settings and how to get there and do it yourself. I haven't ever reached a temp of 82C with the combinations of the cooler and the settings and I'm set at 5.2GHz while giving 150% on CinebenchR23.

Thanks, I suspected those temps were much to high. I ran thru the procedure for cleaning the cpu and it's matching heatsink routine. I think we've both contributed to this problem covering nearly if not all approaches. Ah, I learned a lot from this forum but I would like to pass on the ability for contacts to oxidize. Including processors and heatsinks. Moisture in the air or living by the seaside can really cause problems. I talked with a metallurgist about oxidation and he said that the oxide can be harder than the original metal. Although I've never checked it seems possible the oxidation may not be a decent heat exchanger. Someday I'll look that up. Pizza just came. true. lol

The 200 watts is on a 13700k, which is easier to cool due to larger die / more cores. So yeah, it's expected to thermal throttle with a 14600k at 160-180w.

Thanks for all the answers

I downloaded lastest bios and ME (0x129) , didn't even knew there was whole insitability problem with 13th and 14th so thanks for warning.

Cleaned and re-applied thermal paste

Added one more fan to the radiator of cpu cooler

I changed setting to tower cooler in bios and lowered C when fans supposed to get %100.

Realized im too stupid to undervolt , looks too complex for me so i didn't do it.

End result is pretty much same , looks 1-2C° lower across the board.

Tried cinebench , same results with CPU-Z stress test

edit: changing CPU Lite load on bios mattered big time (so if im not wrong basically it undervolts automatically). Not sure how much performance i lost but i'll use it until i buying new cooler so thanks everyone , i think thats the solution at least for me. There was better modes for temps but i decided staying at mode 7 , it still peaks 91C but doesn't look like there is a much performance loss when i look here

@EvilDuckling I was a bit intimidated by going in to the Bios settings and messing with things too. If you load the videos on your phone or tablet and watch as you actually do it, it makes a huge difference. The middle video has a lot more technical stuff that I only went into after the 1st and 3rd videos, but there's definitely some gold there when you focus on your board brand and tweak the voltages manually.

What I found is that the performance doesn't change a whole lot - and it's clear from the results at the end of the 1st and 3rd video - when you carefully drop the voltage to the CPU. I'll have to check what I settled on, but I think it was 1.15-1.18V, where the temps were consistent at 79C - across the board - while still running stable at the max GHz and the Cinebench23 was showing the CPU at 150%. No bouncing GHz's on HWMonitor, completely constant thru out the test. The point here is that by doing the manual voltage change you can tweak it down, so that the temps never get to 90C while still operating at that top performance level.

Anyway, good luck. I'm glad the videos were helpful.

EDIT: BTW, make sure that when you get your new cooler, that you begin by selecting the "Box Cooler" or whatever that setting in Bios. There are 3 settings with an MSI MOBO, at least, 1 - stock cooler, 2 - Box Cooler, and 3 - Water Cooler. The water cooler setting maxes all settings including voltages. The box cooler settings are middling, but they can be tuned down while still maintaining the same high performance.
