Question Calling all Intel Core i9-9900KS experts ?

[Baconaman]

Greetings, I need some advice. Before I got all old and stuff I would be the one answering this question instead of asking it, but I have not kept up with technology the last couple decades or so the way I did to previous few decades (I was over-clocking my Celeron in the early/mid '90s.)

Background: A few years ago my teenage gamer son purchased a used system with an
Intel Core i9-9900KS CPU that had been de-lidded with a Cooler Master water-cooling system attached. Pretty much from the day he got it, (which is probably the reason it was so affordable), it was running hot. He tried adjusting voltages and stuff but couldn't get anything stable that fixed the overheating so gave up and just ran it that way. So, many many hours followed Overwatching and other games with the fans cycling on and off running around 100*C. It would drop down to 60ish while idling but when processing it would average around 100. When he retired the system and pulled his GPU a couple months ago it was still preforming about the same as it always had so I thought maybe there might be some life left.

So, is it worth messing with?

Should I attempt to relid it and see if it will run cooler with a convention heatsync?

Is it possible to find a replacement lid since he doesn't have the original?

Leave the lid off and try a different cooler?

Anyone been down this road before with this processor?

I appreciate any help on this and thanks in advance.

FYI I'm still using the last system I built using a Xenon X3480 so it's only up from here.

100 fahrenheit is 37-38 degreed celsius...that's freezing cold for being under load.
If it is 100 celsius then yes, that would be hot, it would still be below the limit of the cpu but it would be hot.

Oops. Should have put a "C" there. I edited the post. Thanks for catching that.

Water coolers can't live long enough, considering that it's installed on a 9900k system. Get it off and buy a cheap dual-tower cooler instead. (I don't know how it's called in English, check Deepcool AG620 as an example, it has two "towers" ) It should only cost 20$.
It's common that coolers are packed with a small package of thermal paste, and most CPU coolers provide LGA1151 installing toolkit too, but not every cooler do that, check it carefully before buying.

Additionally, Why do your son purchase that 9900k platform? If I'm the one to make the decision I'll get an 12100 platform instead.

There are some productions of copper ihs for CPUs
Just an example, it might be worth it to look for a good quality maker to ensure good fit and no gaps and so on.

Also you would need quite some knowledge and experience in putting some liquid metal or other tim component directly on the die, it is pretty dangerous just to remove the current set up since the die is pretty sensible to any kind of pressure so even a small wrong move could break the CPU.

If the original seller is not just a stranger then it might be worth it to ask them to help.

But really you should start with giving us more info, like what clocks you are running at now, if it is overclocked it might be running fine even if it is 100° you could just dial it back a bit. Undervolting does not decrease overclocking it does the opposite reducing the volts allows the CPU to draw more watts so it clocks higher.

Check to see if the water block on the cpu is loose, it almost sounds like its not making contact with the chip. If there is no IHS be careful as you can damage the chip its self. If you're putting an IHS on, clean the chip and apply a thin layer of thermal past. Set the CPU back into the socket, place a little dab of silicone on the corners of the IHS that contact the PCB board. Place the IHS ontop of the cpu in the socket and then close the retention baracket, it should hlep align the IHS to cpu and hold it in place till the silicone dries.



Pick this up, Copper IHS when i delided my 8700K i used this, pulled off the old IHS, liquid metal, and used the new copper IHS. Was able to do 5.1GHz all core with no AVX offset on a Cryorig R1 ultimate cooler.
