i7 8700k Cooler help

[xanderbot2000]

My current PC build is
Case: Cooler Master MasterBox Pro 5
Graphics cards: MSi Gaming X GTX 1070
RAM: Corsair Vengeance LPX DDR4 2x8GB 3000mhz
CPU: i7-8700k
Motherboard: Z370 Aorus Gaming 7

I was wondering what I should get for a cooler for the 8700k. I don't plan on pushing the limits of overclocking but I do plan on overclocking to about 4.6-4.7 GHZ range.

What is your budget?Do you have a preference in terms of AIO or air coolers?

Budget isn't a huge problem 150 maybe 200 is max I really want to spend. As for AIO or air cooler I'm leaning more towards air cooler but not completely against AIO if it is recommended for the CPU.

Well when it comes to air coolers I find it hard to recommend anything but Noctua. Top notch products from a company that specialises in that field. In particular, if it fits in your build, the nh-d15 is an amazing choice.

AIO is generally "recommended" but you don't need it, especially when sticking with ~4.7ghz six core. If you don't care about seeing really low numbers on your CPU temperature readings, it doesn't matter, you shouldn't get near your TJ Max during any real workload.

The NH-D15 is probably the best for air cooling, but it's large and not very pretty. Front fan may need to be moved up 2mm for RAM clearance (should be just enough for your case). Otherwise there's the NH-D15S, which just doesn't have the front fan (also a little cheaper) and performs almost exactly the same. Some also say these Noctua coolers have simpler installation than many other air coolers. With the i7 8700k at 4.7ghz I would be surprised if you got over 70C during load or reached 70C with Prime95 Blend or In-place Large FFT stress testing. Edit: If you use Prime95 to stress test (especially with Small FFTs) you should use version 26.6.

I'll tell you that large heat sinks might be cumbersome to install with the Z370 Aorus Gaming 7 (at least something like the Cooler Master MA620P) because the VRM "heat sinks" are pretty obtrusive and can make getting angles to torque things hard ( This might not end up being a problem if you go NH-D15, though). It will probably be considerably easier (or more plausible) to install the heat sink before you install the Aorus G7 into the case, if you weren't planning on that already.

Just make sure when deciding on an air cooler that you check for RAM clearance and what height your case supports. You can of course get an AIO, simple installation, mostly minor (but realistic) risk involved [you can read some forum posts about accidents], but if you're not comfortable there's no need to go liquid get perfectly safe temps with those clocks, even with the 8700k.

either the NH-D15 by Noctua or the Thermalright Silver Arrow IB-E Extreme (if you got enough space). The Thermalright Archon IB-E X2.

Thermalright is often overlooked as they don't spend so much on marketing as Noctua, but they make pretty decent, powerful and quiet coolers

Either the Noctua NH D15 or Be Quiet Dark Rock Pro 4

You might fare better, but you might thermal throttle during Prime95 Small FFTs, but this kind of stress test doesn't represent real load performance.

Actually you are misinformed.

Thank you. Despite my disabling AVX in Prime95 V26.6+ it apparently wasn't working properly.
Prime95 26.6 doesn't even get into 90C with the Small FFTs stress testing. The newer versions in general seem to have problems with 8th Gen processors, I couldn't successfully modify the new version but the old version is running as expected.
