I installed an NZXT X73 onto a 10900K, even at max pump and fanspeed the cooler is struggling to maintain temperatures below 90c if the power draw is in excess of 250w.

Is this bad mount? Or something that's normal?

Do I have to upgrade to open loop in order to keep temps lower and/or want to push more power draw?
 
you can try a re-paste and re-mount but if i recall right that is about right for an aio. is the aio mounted as an intake?

edit: "using a 240 mm EVGA AIO was enough to run the CPU at 5.0 GHz while stress testing with Prime95 small FFTs. Moving up to the EK Predator 360 mm CLC we were able to squeeze another 100 MHz from the 10900K but the temperatures were still creeping over 90°C and the TjMax for this CPU is 100°C at which point this motherboard will throttle the CPU"

I actually just repasted the CPU since I thought something was wrong, contact is actually fine

using GD900 thermal paste



since that aio is better than the X73 on paper, do you think I've reached the thermal limit for the 10900K on this cooler?

if its setup as intake and getting fresh air, fans and pump are maxed then yes its at its limits.
 
I'm seeing something similar with my 9900K at 5.0 / 4.9 AVX, using a 280mm AIO with four fans sandwiched around.

Bout the only thing I can do is get a bigger rad or try delidding, or both.

even the factory die sanding / thinner silicon doesn't really help in this case?
 
Keep in mind CLC waterblocks and pumps are marginal at best and when on high heat applications simply can't move heat from CPU into water and to radiator fast enough. Thier pumps are only flowing about 40-60L/h,about as much as health adult can urinate. I say about because they don't tell us what their flowrate and lift is .. obviously because it is so extremely low. D5, most popular custom loop pump moves up to 1500 L/h. Pump flowrate testing has shown dramatic increases in cooling ability sd flowrate increases from 40-60L/h all the way up to 400-500L/h .. even higher with high heat CPUs.

Below is testing at 420-1200L/h:
Comparison test
We’ve set up a testing station so we can compare results of the 3 pumps, we’ve set it up in an open plan so it doesn’t have a case, the CPU is a 5820K, a 240ml radiator with an XSPC CPU water block, 32GB of Corsair DDR4 2400MHz Quad channel RAM, Asus X99-A Motherboard, a Corsair RM750 PSU, a Samsung 850 EVO 250GB SSD, Nvidia GTX 980 4GB and Windows 10 Home, we’ve over clocked this rig to 4.7GHz at 1.35 volts giving it a fairly big boost.

The cooling loop comprises of a XSPC EX240 dual Corsair 31-000403fan radiator, XSPC Raza CPU Waterblock and 90cm of 12/16mm green XPSC UV Tubing and simple distilled water. The pump for each test varies.

Each test was carried out by running Aida 64 for 15 minutes and then recording the CPU temperature in HW Monitor. You can see how even going from 420L/h to 450L/h lowers temp 1c, dropping 6c with 1200L/h.

Flowrate of 7.0L/m = 420L/h eas 74c
Flowrate of 7.5L/m = 450L/h was 73c
Flowrate of 20 L/m= 1200L/h was 67c

Below is direct from nvidia saying 1GPM is goal. 1 gallon per minute is 227.1247070L/h. That is 4 times or more coolant flowing than CLCs!

"The pump is obviously the heart of your loop. Its purpose is no secret. In todays watercooling you performance relies on flow rate (among other things). As the loops flow increases from 0GPM to 1GPM we see an almost linear increase in performance which begins to level out at about 1GPM. Anything over 1GPM only offers a minimal performance increase, though the increase is still there. Shooting for the 1GPM mark should be your goal with anything over 1GPM an added bonus"

Can't do open loop at this time though :|


My advice is simple: set your PL2 and PL1 power limits and durations, and use offset overclocking.
That way you are doing what the chip is designed to do. You also get peak speed if load isn’t high, which leads to better responsiveness

I have detailed my experiences here: https://hardforum.com/threads/quick...6xxx-7xxx-8xxx-9xxx-10xxx-processors.1996926/

Thanks, I'll check out the tutorial.

Don't know where on our big blue marble you are, but if you can get a Swiftech Drive X3 AIO (not CLC) is quite good. All components have threaded fittings, has copper radiator, fill port, etc. Pump is variable speed 1200-3000rpm 660L/h & 2.8m/H2O lift. They have 240mm radiator or 360mm readiator systems.
Link below to specs:
http://www.swiftech.com/drive-x3-aio.aspx#tab3

Alphacool Eisbaer Extreme AIO with copper radiator, threaded fittings, quick connects for adding components, fill port and VPP755 V.3 D5 pump rated 1500L/h.
https://www.alphacool.com/eisbaer-extreme-280-black-edition-cpu-aio

Alphacool Eisbaer AIO is not as extreme with Alphacool DC-LT pump rated 100L/h, so not as good as above, but still about twice what CLCs flow.

Alphacool's customer support seems good now, but in the past there have been some problems, so best to buy from local dealer rather than direct from them in Germany.

Too many horror stories on the watercooling discord to even consider the swiftech units.



I already have some watercooling parts, just don't have the money to fully assemble an open loop right now.
 
I have my 10900k overclocked to [email protected] and -1AVX and my temps don't break 93 with a artic 360 II rev2 and two weeks ago I had the NZXT X63 and it never broke 94 using prime 95 torture test. I am curious about how much difference an open loop would make. Prices are pretty steep. What are you doing to get those temps?
 
It’s a cool design, but it’s aluminum.
Reminds me of Alphacool combo products.
I guess all those partial EK aluminum loops you can get cheap would work out.
