Question Do I have to change my cooling?

[cavaler1983]

I want to upgrade my CPU from i7 8700k to i9 9900k and 0C . . The TDP of the I9 9900K is 95 W and the TDP of Enermax ETS-T50 AXE is according to the site of Enermax os 230 W but I am not sure .The case support

Radiator Support	Front 2 x 140 or 2 x 120mm Rear 1 x 120mm
Clearance	GPU Clearance With Radiator: 334mm GPU Clearance Without Radiator: 364mm CPU Cooler: 161mm

And of course what I could expect from OC on this z270 MB ? I know the MB is high end and supports i9 9900k OC

This is my present configuration
CPU Intel Core i7-8700K
NZXT S340 Razer Special Edition
Asus ROG MAXIMUS X HERO
VGA Asus ROG 1080ti Strix
Cooler Enermax ETS-T50 AXE (ETS-T50A-FSS))
RAM Corsair VENGEANCE® LPX 32GB (4 x 8GB) DDR4 DRAM 3000MHz C15 Memory Kit - Black

SSD Western Digital Blue 3D NAND 1TB M.2 SATA3
HDD Toshiba N300 3.5 6TB 7200rpm 128MB SATA3
HDD Hitachi Ultrastar 7K2 3.5 2TB 7200rpm 128MB SATA3
HDD Western Digital Caviar Green 1.5TB

Yeah, a 92mm heatsink isn't going to cut it with a 9900K.

If you're going to OC, a 280mm AIO would be most people's recommendation.

I don't believe any Z370 motherboard is up to the task of handling an overclocked 9900K, so you're also looking at a new Z390 board as well.

The Maximus X Hero is a pretty BA board.

I would say give it a try. That coller can handle stock & boost, but that's it. With good paste 5Ghz, but that's the limit. mobo will also give up around 5.1 Ghz.

If I recall most of what I have seen on 9900k's and overclocking, very few have made it much beyond 5.1 or 5.2 Ghz. The chips themselves have been binned at nearly the top of the hierarchy and can only be sold if they can support the clock speeds and automatic boost to 5Ghz while remaining stable.

I have a 9700k and have had zero reason to overclock it because of how well it performs out of the box. I do like knowing that 'I can' if I want to, but nothing is really driving me to do so.

@ rubix - Does your mobo enable MCE and run all 8 cores at 4.9GHz though? That's technically OCing.

 

[rubix_1011]

Yes, I can set those distinctly and independently on my board.

Overclocking, MCE or none of the above: You'll still need a minimum a 280mm AIO for a i9 9900k. Especially if you have a high end graphics card that raises chassis temperature.
