Best way to route airflow for custom loop?

I'm going to be trying my first custom loop. All hardline tubing. Single 280 mm Corsair radiator mounted in the front with two QL140 fans. These are low speed fancy RGB 140mm fans that only run at 1250 RPM. It's going in a NZXT Elite H510 case. I'll be cooling a 2080Ti and 9700k, both being overclocked so I suspect it's going to pump out a ton of heat. The question is whether I should pull air from in the case and have it exhaust out the front or take clean air in from outside and pump the heat into the case. Obviously pumping in 500w of heat into the case is not the most ideal, but I am thinking that if I try to take the air from inside the case and pump that through the radiator, it's going to result in increased coolant temp because the air coming into the radiator will hotter from inside the case than outside.

What do you think?

The 510 has rear exhaust and top fan mounting so draw cold air in, case has filters so shouldn't be a problem with dust either

IMO you will not have enough RAD surface area. With a single RAD you would need 3000 plus rpm fans, even then I think you would have a hard time cooling both the cpu and gpu. You can always try and see what the results are.

I am firmly entrenched in the all RADs in camp.

Bad case and waaaay too small radiator surface for your components,especially OC ed ,it will run very hot or very loud . I'd get a new case and an extra rad . Or just stay on air.

The main advantage of water cooling is increased cooling capacity & reduced acoustics. With the proposed setup, you are spending more money for likely similar performance of an air cooled setup. I disagree with the comments about "not enough rad" in the context of requirements. The 280mm radiator will dissipate that heat without your components over heating. That being said... it's not advised (due to cost / effort of what you are proposing).

For reference, I ran a 3930k & GTX 780 (380w combined TDP) on a single 360mm radiator with 3 SP120's at approx. 1200 rpm. Cooling performance was fine but I would of preferred more rad. I was just limited on budget. You can check my build logs for stats if curious. Delta varied between 15 to 30c based on load, OC etc.

Second, due to the construction of radiators (dense arrangement of copper / aluminium fins), you should optimize your fan selection for static pressure.

You can see fan spec comparison here:

QL140 specs vs. SP 120 specs

EDIT: As you can see, the SP120s, a smaller and cheaper fan (half the cost) performs a bit better. That being said, Corsair fans are not that good. I'm not too knowledgeable on the best fans (performance / noise) but others can chime in here. I'd be looking at something like this Noctua NF-P14s redux-1500 PWM based off a quick google search.

Cheaper than the Corsair LED fans you've selected, better performance, and similar dBA...

What do you think?
Given the context, 280mm radiator for two components, you should try to follow the rule of thumb before solving your direction of air flow.

120mm radiator per component + extra 120mm radiator.

If you are limited in radiator size and you're concerned with the stability of other components (Motherboard), ensure you have additional fans to provide fresh air to those components. Finally, you can just pick a direction that is most suitable for where your case will be located.

If you had more rad surface area, it would not be as critical to identify the additional fans but you're walking a fine line here...

To summarize, I advise the following following:

1. Increase radiator size.
2. Revise case if increased radiator size is not feasible.
3. If 1 & 2 are not followed, ensure you have additional fans for other components (motherboard etc.)

Hope this helps

A single 240 radiator only in push at no more then 1250 rpm's? I don't think it'll matter exhaust or intake, that's no where near enough radiator space and even if it was that's not even close to enough fan power.

sorry, there is a long laundry list of things that are wrong.

that corsair rad is just a rebranded HWL 280GTS:


just slightly higher than your fan speed (let alone accounting that the review used better fans - noctua leaf blowers) will give you enough for one of the two blocks (cpu/gpu). fwiw, i have the EK CE 280 ([3770k]4.6/1.28v -[980ti bios modded 360watts] 1480/1.27v) - and i had to replace the 1.6K vadar fans with noctua 3K fans to not struggle at keeping a 10c (or less) water delta while gaming.

i highly suggest looking at a bigger rad with better (faster!) fans which will mean using another case.

Remember the golden rule of statistics: A personal sample size of one is a sufficient basis upon which to draw universal conclusions.

If you need help: Upload the computer to Dropbox and provide a link to it so others may download it to examine and give advice for repairs.

Agree with others. While it could be done in that case, you'd be better off grabbing a case better suited for multiple rad mounting so you can also take advantage of lowered acoustics and not have to run RPMs as loud on the radiator fans.

Best way to route airflow for custom loop?

I agree with the prior posts. I also like push/pull arrangements. The rad size is your biggest issue. The 120/140mm per component in loop with and additional 120/140mm is a tried and true standard. Allows for not only cooling the components, but the additional heat the OCs you mentioned will put out. Static pressure is the best measure of a fan in combination with a radiator. I shy away from RGB for my radiators, as many lack good static pressure. Filters are a must, but be prepared to break your loop down to change the fluid and dust the inside of your case at regular intervals. Dust is the enemy. Clean the filters regularly too. I always have the heat go out of the case from the rads and the cool air into the case and over the components. Ambient temp of the room is the best gauge of how low you can go. If the air starts off warm, it hard to get the components cooler than that.

Edit: I forgot to mention how I figure out how many intake fans I need. I usually go with the size of the rads. If the rad is 360, I use 3 (as a minimum) or 4 120mm fans. This allows me to figure my case needs. This is the hard part. Finding a case with the ability to have the intake flow and ability to put in a large enough radiator. In one case I have two 480mm rads in push/pull and have 11 intake fans. Yes it is a large case, but that is what you need based on the number of components you are cooling. In the case I am cooling 3 780Tis on one loop and the motherboard, CPU and RAM on the other. Temps are great and have always been. Time for an upgrade though.

I am currently running a 1080Ti overclocked and I am cooling it with an H80iV2 and a single 2000 RPM fan. It does a great job and it's less than half the size of the radiator I bought. I feel like I could connect a 2080Ti to it and still be fine and it's a fair bit smaller than the 280 I got.

Attached is a photo of my current build and the temps have been perfectly fine.

I could add another 120mm radiator to the back or top of the case. I am not sure if the back of the case or the top would be better for a 120mm extra rad.
