Old H115i vs H115i Platinum for 9900k

Jizzy · 26 Jul 2019 at 22:30

I currently am using the old H115i from my old system, on my new 9900k system @ 3.6ghz (removing the mobo stock turbo boost), but getting hot temps, 52-55c idle. Running CoD WW2 on about 20% cpu load goes up to 75-85c.
Running a CPUZ stress on it makes it raise up very quickly to over 95c, it would continue to climb higher but turn off the stress before it does to prevent damage etc.

PC Specs:
I9 9900k @ 3.6ghz
Z390 Aorus Master mobo
Corsair Dominator Platinum (2 x 16GB) 3200MHz
2 x MSI seahawk 1080ti (AIO versions)
2 x m.2 nvme drives, 1tb & 500gb
TUF GT501 case
Corsair H115i cooler (with standard fans which were included)

So I've tried reapplying thermal paste, I use Cooler Master Mastergel Pro. 3 times all with very similar results.
The temps mentioned above are after I've reduced the volts to 1.1v in bios, CPUZ shows 1.068 on idle

I should also mention, this is with the fans on the H115i set at 100% (2200rpm) all the time which is very noisy)

I got a little sidetracked and a ended up with a long explanation, but what I want to know if there is much of a need to upgrade my old H115i to the new platinum or if all they've done is added RGB on the block and added the ML fans?
So I could just get the ML140 pro fans separately and not worry about RGB to save money?

Overclockers doesn't sell the old H115i so I can't link to a product on here, so will link direct to corsairs page (if not allowed please remove the link)

Hi Jizzy

I have the same cpu and board as you, but with an antec 360mm aio cooler, at idle today when it is very hot indoors, the idle temp is around 35 deg.

what made you remove the stock turbo boost? and how did you do it please?

thanks

If you use V VOUT within HWiNFO64 that is supposedly a more accurate measurement of vcore for his motherboard. Perhaps use that as a measurement when under load, as well as idle.
By default I found this board tended to add more vcore voltage to the 9900k for me than what was needed.

See below images for bios settings and screenshots of monitoring programs. As you can see in the first one, idling in bios is @ 72c.

In windows after about 5 mins idling after booting:
Core temp V: 1.0280
HWiNFO64 V: 1.0283
CPUZ V: 1.068

After 2 minutes of CPUZ stress CPU
Core temp V: 0.9922
HWiNFO64 V: 0.9894
CPUZ V: 0.996

Hi Ian,
If you look through my screenshots in bios above you'll see I disabled it in there. As a comparison. my graphics cards are running @ 27c idle, but my cpu is 52c idle.

Thank you Jizzy. I'm running f7 bios, see that you have f9.
I wonder if that makes any difference?

I had to upgrade from F7 to F9 to even get it to boot and install windows, see this thread: https://forums.overclockers.co.uk/threads/new-build-issues.18860378/#post-32887394

Just looking over everything again, I've noticed something which might be causing the additonal heat?

My mobo on corsair link is showing VCPU 1.42v on idle and 1.33 on load where as the other applications were showing less then 1? you can see in the screenshots above.
