Help about cooling 8700k 5ghz
Hello,
I’m excited about my recent high overclocks on the I7 8700K using an EK S240. The results are impressive—around 69-70°C during stress tests, with lower temps in other scenarios. However, I’m concerned my VRAM is getting hotter, so I’m considering a monoblock upgrade. I’m also unsure if cooling the motherboard and CPU together will help or if it’s better to focus on just the CPU.
Regarding radiators, I’m planning to add a GPU in the future and want to know if buying an EK XE 360 with 3000rpm fans would lower temperatures more effectively than my current setup. Would it work well for both the CPU and GPU, or should I stick with my 25mm radiator?
Here’s my rig setup:
CPU: Intel i7 8700K 5GHZ OC
FAN: EKWB 240S KIT
Motherboard: Asus Prime-a Z370
GPU: MSI GTX 1080ti Gaming X
RAM: ADATA 16gb 3000mhz
PSU: EVGA G2 750W
SSD: Samsung 960 EVO 256gb
HDD: WD 1tb 7200RPM
Case: Corsair Crystal 570x RGB
What advice do you have on these upgrades?
I've never realized a monoblock was beneficial. A thicker radiator enhances cooling by providing a larger surface for the liquid to dissipate heat.
A bigger radiator provides more cooling than a monoblock could, but if you can afford it, the monoblock also helps stabilize the motherboard’s temperature. You might also ensure sufficient airflow across the motherboard itself—this should be enough on its own.
For thicker radiators such as the XE 360, running the 3000 rpm fans in pull mode is more effective than in push mode. I own some 3000 rpm Scythe Ultra Kaze units; they perform well, but they function better by drawing air through the heat exchanger rather than forcing it through.

I plan to use Vardar 3000 RPM and try it out. I’m not concerned with cost when I want to improve my PC, not that I’m rich. Just wanting to do things right, so I might upgrade to a new motherboard like the Asus Maximus Hero, add a 60mm thick radiator XE 360 with fans, and hopefully see better overclocking results. Are my current temperatures suitable for a 5 GHz processor?
