Yeah, my response got stuck up above, but I believe the Alienware AIO is good for about 150.

OP seems to back down from air cooler.

Hey, I just found a 47 mm tall TDP 115W all copper low profile air cooler, for the next person wondering about possible air no water.

CRYORIG C7 Cu is the newest low profile CPU cooler

http://www.cryorig.com/c7cu.php

it is 675 g, all copper. is it too heavy?

 


Yeah, they have a graphene coated one with a higher rated TDP too (not to be confused with the lower end graphene coated non-copper version)  The copper graphene and copper ones are imported and hard to find in the US, they often can sell for close to $100 due to the demand from SFF enthusiasts and low supply.

Or yeah a ruler, I have a ruler. That's 7 centimeters... I dunno tho, 5 mm above the fan might not be an optimal configuration... I got a real good deal on this Alienware so I don't regret it, no way the parts separately could have come under the price I paid.  But good LORD do I hate this case.

And then there is this ultra low profile cooler, only 27 mm tall which will definitely fit R8.

Thermaltake Engine 27 1U Low-Profile CPU Cooler https://www.thermaltakeusa.com/engine-27.html


The guy has an unlocked CPU.  This cooler is not for unlocked CPUs.  It's only rated for 70W.  All of the 8th/9th gen unlocked CPUs are 95W tpd and can exceed that, with just Turbo boost (no OC).

AIO better than air cooling in Aurora R10.  Search for R8 AIO upgrade.

I have no idea what my CPU is pulling.. but I looked up H60 by Corsair.  I guess I am just skeptical of technology that I don't understand (Merc knows big heatsink and big fan make cold!  Merc no understand tiny thing with tubes coming off of it!)  I am doing a fairly mild overclock, with voltage set to 1.275 (I'd like to try to go lower, maybe later.)  But I reckon this damn thing is working ok.

Thanks for everyone's input... the solution is, just close my eyes and hope for the best.   Thanks.

For example, there's only 1 copper one listed on ebay right now.  It is $189.99.

Interesting... the thing is though, with that huge ridiculous power holder monstrosity, any fan you have in there is just going to be blowing air directly onto the PSU enclosure, or (if mounted upside down) onto the CPU but... man, there's just no room.  I guess they used liquid cooling for a reason.  Maybe I should be looking for higher quality liquid coolers.  Thing is, I'm totally out of my wheelhouse, I dunno how these things work.

 

EDIT: What I mean is, you could fit one of these low-profile fans/heatsinks, but there would be no effective airflow.

I do not know what gpu spec you have and whether it is physically feasible in R8, but if a power hungry gpu can use liquid cooling in there it will certainly help lower chassis air temp which in turn lowers cpu temp even though cpu is cooled by AIO.

Prime95 got the core up to 96C and package to 170W... I think I'm gonna try to back the CPU voltage to 1.25 (from 1.275) and see if I can get the temps lower while keeping the 4.9ghz overclock stable.  Ohhhh why am I doing this to myself...

it is a i7-9700K.  I currently have it using 1.275V and overclocked to 4.9ghz (max).  It seems to be stable... I dunno what the power draw on that is in wattage.  But you're probably right.  I'm also probably under-estimating this generic Alienware liquid cooler on the thing... oh well, I will live with it!  Thanks for everyone's help.

OK so while doing a fairly intensive graphics processing job (converting image files from one format to another for flight simulator photo-imagery), I gave the Intel Extreme Tuning Utility a quick 5 minute spin:

Max CPU Temp: 90C

Top CPU Package wattage: 164W

There was no throttling that I could see, but there mighta been some.  At any rate.. "OP backed off air cooling", is accurate cuz nothing will fit* and I'm not confident that there's enough room in the case for adequate airflow!  Do you guys agree with this?  Considering the benchmark above...

* EDIT: A few coolers will fit, but they seem expensive and the space for airflow is troubling... I'm beginning to find newfound faith in the AIO.

Hmmm... that looks pretty good.  I have a bad feeling tho, that it wont fit.  I'll take a look.  Do you think that would be more effective than the stock Alienware Aurora R8 liquid cooler?  I'm kinda flying blind here... Thanks for the research you did for me, I really appreciate it.

Voltage of 1.250 no good, got power throttling and the CPU was only hitting 3.9ghz or so.  Put it back up to 1.275V and it seems fast and stable, hitting 4.9Ghz.  I just hate the thought of that little plate on top of the CPU, with a gap of a few centimetres between it and that huge ugly stupid PSU mounted right in front of it.

Also my CPU gets up to 92C or so under heavy load, which... Ohh bother.  Maybe I'll buy one of those big stand-
