Radiator & Fan help

Van Diemen · 19 Feb 2019 at 14:02

Will the following single 280mm rad be sufficient to cool a 9900K & RTX 2080Ti?

Plan to use these fans in pull config with it:

or will this 360 serve me better?
https://www.overclockers.co.uk/ek-water-blocks-ek-coolstream-pe-360-triple-radiator-wc-488-ek.html

are there any rads I should consider?

my case is a Phanteks Evolv m-atx, gives me 75mm of space between the front mount point & GPU, ideally would like to keep the rad/fan combo down to about 70mm

I'd go for the 360 rad if it fits. Should be enough to cool both cpu and gpu.

if overclocking, i wouldn't run a 9900k and 2080ti with just a single 280mm or 360mm rad. that's just asking for trouble.

might need San Ace's trusty 38mm thick 120's at 40dB!

to do a single 360 rad, you'd be looking at Black ICE GTX 360 or PE 360 but with silent wings 3 140mm that are running at 100% or high speed version for same sound rating but more airflow and static pressure

your looking at 600w to cool, PE 360 can handle 597w MAX with EK Vador fans AT MAX! XE 360 from EKWB is 740w again this is running fans at 90-100%...

water temp with PE will be warm, i mean you'll actually be able to touch the tubes and feel the heat , 35-45c... if you can push pull! great, means can shift more air and turn down the fans to lower speed at cost of size increase and cost!

To be fair, I've cooled an overclocked 3770k + quadfire 7990s with 480mm of alphacool ut60 albeit with 1850 rpm gentle typhoons. It is doable. Just not really recommended. My max water temp was 45c iirc. Pump fails at 60c

Thanks for the link to the configurator.
I may have to consider going with 2 rads, just need to work out what fits where.
Really don't want to get a new case

Gentle Typhoons.... sweet spot right there ! swiftech tried so hard to copy too

evolve matx with SE 360 and silent wing 3 on MAX

I Believe 240 will fit in the top as well, or 280 and 240 but DO NOT GET SE versions

this is what you want !!

Not really that hard to work out.
Oc 9900k 250w max tdp
Oc 2080ti 300w max tdp
You'll need at minimum 550w heat dissipation.
200w per 120mm is usually the max. Assuming thick rads + high power high quality fans like the gentle typhoons
Ideally 120-150w per 120mm.
So you should aim for 480mm ideally

Is there any particular reason I should avoid the SE?

Van Diemen · 19 Feb 2019 at 15:32

Theoretically I can go 38mm 360 in the front (as I forgot the factor in the extra 12mm the EK GPU black adds) with a slim 240 on top.

Worst performing 360 rad! It's slim yes but other slim rads like xspc or alphacool perform better

Van Diemen · 19 Feb 2019 at 16:21

Think the following should work & fit:

XSPC TX 240 Top
XSPC EX 360 Front

Why don't the rad specs include heat dissipation figures?

Because these have multiple variables

I basically used all the info from this website to plan my water-cooling build

My basket so far is:

My basket at Overclockers UK:

1 x EK Water Blocks EK-Velocity Intel CPU Water Block - Nickel + Plexi= £69.95
1 x EK Water Blocks EK-Vector RTX 2080 Ti RGB Founders Edition Water Block - Nickel + Plexi= £129.95
1 x EK Water Blocks EK-XRES 140 DDC 3.2 PWM Elite (incl. pump)= £129.95
1 x EK Water Blocks EK-UNI Pump Bracket (140mm FAN) Vertical= £14.99
1 x XSPC TX240 Ultra Thin Copper Dual Fan Radiator - White= £44.99
1 x XSPC EX360 Triple Fan Radiator (White)= £53.99

Total: £454.32 (includes shipping: £10.50)

I still need to add fans, fittings, tubing & coolant

LuckyBenski · 19 Feb 2019 at 19:22

If the uATX version is anything like the ATX Evolv, you really need to think about airflow. The front is very restrictive and the top moreso, to the point where you're recirculating air from the top radiator into itself. That's an awful lot of heat in an awfully small restrictive case.

I would suggest at least 480mm of rad space for those components, tempted for more like 5-6 slots, with thick radiators and loud fan speeds.

On the plus side, it sounds like you might not have planned for the front cavity? In my ATX you can mount fans in a channel on the outside of the case behind the fascia. So push pull is possible.

FYI that EX radiator although it sounds thicker at 35mm the actual radiator is about 10mm thinner at least inside the frame... To the point where it might as well be the thinner one there also. If you can fit a chunkier one in then have a look at maybe alphacool or similar.

Thanks for the above info, I did notice this.

I found some time this morning to take some proper measurements.
With my case I will have 68mm between the end of the GPU block and the front mount position.
Adding a fan leaves me with a total of 43mm of rad space, my guess is 35mm rad would be my max, this leaves 8mm between GPU and fan/rad. Or would I be okay with a 40mm leaving 3mm space between rad/fan and GPU block?

You would be ok but I think you mainly find them about 35mm anyway - larger tend to come up 55-60mm. Don’t forget to check how they mount and if there are any raised areas where it would screw as these can add a 5mm here or there.

Extreme rigs radiator roundup is a great start, then narrow down by fit etc.

After a little reading I’m thinking of getting the Hardware Labs Nemesis GTS rads.

360 in front with a 240 or 280 top.
I’m reading that these rads are restrictive, so will the EK DDC 3.2 be powerful enough?
