A place to discuss, share, assist, advise and explore.



 
So Ive only had my 9900k for about a week now - but what I am noticing is that it is quite a warm CPU - I ran Prime 95 for an hour and it quickly thermal throttled on a H115i - and settled at about 85'C on about 4.6Ghz 400Mhz under its max boost speed.

My room has an ambient of about 30'C (its an upstairs loft so it gets quite hot)

I think I need to upgrade my AIO - but im not too sure what to upgrade it to?
 

There are literally only 3 AIO's available to us that can keep it cool.
The best of the bunch would be

MasterLiquid ML360R RGB | Cooler Master

What case and what fan setup are you running?

You really should have done more research before buying this chip. It's an endless struggle to keep it cool with our climate in SA.

No lack of research, I knew it ran hot - I was expecting more of a top end of 80 - as thats what a lot of information points to.

Running:

Phanteks Evolv X (3x 120mm 2x intake, 1x exhaust)
Corsair H115i 280mm (replaced stock fans with 2x EK Vardar 280mm)

9900K - Its a Beast, but its made by muppets.....
Still muppet cpu is fun to have.

Agreed.


My only issue is:

I have a 280mm AIO.... would going 360 really be that much of an improvement?

280x140 = 39200 (surface area)
360x120 = 43200 (surface Area)

Phanteks Evolv X (3x 120mm 2x intake, 1x exhaust) <------- The Problem

Any pc chassis with a sealed/closed front is terrible, unless you have a setup like @GuardianTB

Hmm I would say so - However just note these cpus are poorly made, they dump heat like no-other so will it make a difference - YES - however they will still be hot chips without a doubt.

The evolv X attended to the front panel suffocation issue, while I will admit there is still a temperature increase, it is very well documented in that its restrictive dust filter and inadequate stock fans.

So I'll be swapping out the stock fans with more EK 140mm Vardars.

Do you think waiting for cooler manufacturers to mature towards 9th gen and the hotter chip is wise or will it just be moot?

Would you mind posting your temp results? Say after an hour of prime 95?
 
If I had this chip I would delid if its not already soldered and then use some liquid metal/Conductonaut on the IHS. Pointless going with a normal TIM when you spending a lot of money on an AIO.

Sadly it's the design of the chip that makes it a hot chip(check out debauers youtube channel he explains it perfectly) . There is only so much coolers can do due to cooling surface area and surface contact on the cpu etc.

its soldered from factory - if you want to delid it, it would mean lapping it too.... and I dont really want to risk it

Never delid your 9th gen CPU - you run the risk of taking capacitors off.

If you want to do anything to improve the conductivity, put the CPU on a flat surface with the IHS down. Try spin it. If it doesn’t budge, that’s great.

If it spins like a 10 year olds spinning-top, your IHS could do with lapping.

Google IHS lapping by Der8aur but just know that it essentially voids your warranty since the serial will be removed.

I lapped by 3770 and the temps dropped.
 
I settled for the 9700K since I knew the 9900K would be a nightmare to cool. Even the 9700K easily hits 85'C+ with a custom loop (5GHz @ 1.376v) and draws 200w. Prime95 small FFT's aren't possible since it immediately shoots the temps up to over 100'C. My Strix Z370-G motherboard actually shuts down due to the VRM's overheating when running video encoding for extended periods. Time for a monoblock I guess...

As said above, lapping is the last thing you can try but unless it's seriously uneven you'll gain 3-5'C at the most. And who would want to void the warranty on their brand new R12k i9 chip?

Your cpu just not a great OC'er?
Your V seems high for 5Ghz

Not the best OC'er it seems. I must admit I was also testing worst case scenario with the temps. What voltage are you running for 5GHz?

I guess it also depends what your metric of "stable" is. I was using this mehod. With other "stress tests" I could run 5.1GHz @ 1.32v

5Ghz@1.27 V dead stable. I reckon I could probably get it even lower if i fine tuned a bit.
 
Can everyone who posted in here, please state what motherboard they are running and how stable their RAM overclock is?

Asking for a friend who is suffering CUD.

Thanks

9700K @5Ghz 1.27V under a Nzxt Kraken X62 with a fairly agro fan profile.
Asus Rog Maximus XI Hero
G.Skill TridentZ RGB 3200 16GB (Stock XMP, capable of more but haven't actually done much Ram ocing).

Not a 9900K owner, but useful for reference.

6950X @ 4.2GHz 1.29v under a H150i (still need to voltage tune, should get another few 100 MHz at better temps)
MSI X99 Gaming Pro Carbon
Corsair Vengeance 2400 C14 (Hynix chips) @ 2800 17-17-17-36 (can also go quite a bit more, had them up over 3000 once but temps too high)

Biggest change I made was a high airflow case (CM H500). No more little "hot pocket" over the VRMs - saw a 20C drop in temps (they were knocking 80C before). I run 2x200mm in front of the AIOs 3x120mm, with stock 120mm exhaust out back & another 200mm for top exhaust.

Is a decent air cooler not recommended for the 9900k?
