If you are using both drive cages, the front intakes serve only to cool those drive bays. I am just using the bottom cage, so I have one front exposed, and it doesn't do a whole lot on its own. I have a fan on the drive cage blowing towards the rear. Those top intakes help a lot. Even though I have 5 in 1 out, its more like 3 in 1 out. This definitely isn't the best case out there lol. I've also removed the filters. I am running the front fans at 7v, 12v is pretty loud but moves a lot more air. 120x38 Panaflos.. 100cfm or so at full tilt

Are you referring to my reply to postem? He has Thermaltake Core V41.

GeneO does indeed have Define R4 but has replaced stock garbage Define R4 front case fans with NF-A14 Chromax fans which have decent pressure rating so case flows air just fine. I'm assuming he has removed HDD cages and has SSDs mounted elsewhere so front intakes are only limited by vent size, grill and filter. With all PCIe back slot covers removed for more rear vent area it's even better. Having another of his NF-A14 as bottom intake and extending case feet so case has 30-40mm bottom clearance also improve airflow to bottom vents dramatically.

What case do you have? What is the case fan setup going to be with CPU being air cooled?

You might find the basic guide to how airflow works and how to optimize case airflow in below link of interest.

Hi doyll, thanks for your kind response.
My case is a thermaltake v41.
https://www.thermaltake.com/products...?id=C_00002499

The reason im prone to go back to Air cooling are the follows:
1) I never trusted that much AIOs (or water in general). I must give in that the AIO is keeping good temps for 2 years, it was just when i added an Axis style GPU that i crossed the "magical barrier" (at least for me) of 40c, and rising, of the coolant.
2) Due to current situation in my room, which is posed to change in 6 months, i cant manage to replace the case. The case lies behind, lined with my desk.
3) Even if sound levels are similar, and i dont think so at 1800RPM, AIO is mounted as top exaust, and fans are very near me. With fans inside the case, sound will be dampened.

Currently, 2 140 ML fans @ 60%, 1 120mm ML fan jury rigged as top intake, so 3 intake fans, and 1 rear 120mm jetflow fan @ 60%.
All fans with curves going up to 90%, except radiator fans, those make very bad noises when changing rotation, so usually i keep radiator fans around 1200-1300 RPM, and during the day, due to room temperature around 31-32c, i blast 1800-1900RPM to keep coolant below 40c.
PSU is with fan turned inside case, mostly due to very dusty enviroment.

GPU is always kept below 67c due to zotac fan profiles, but its okay in noise terms to me.

With Noctua DH15 or DH15s, i expect to keep temperatures under control without having to account for coolant temps, while keeping cpu fans at most the max of noctua.
With AIO, even with liquid > 42c, cpu never goes beyond 71c, its 5ghz 1.34v and dellided, there are 3c at most core temperature delta.

The case can support 3 120 or 140mm top fans or up to 2 200mm fans. What you think would be best for air channeling? closing the top or having fans on it? It really annoys me too that with the top grill, i have dust and other particles that often falls into the case.
I was never much of a fan of top grills as it exposes the case to every kind of contaminants than can fall.
Get some the new Arctic p series fans and turn the flow to inlet. That will lower both noise and temp.

Yep. There is a decent airflow from the front but it is certainly restrictive.

Hi just to update current situation.
Replaced H110i gtx with Noctua D15. Unfortunally i wasnt able to fit both fans inside my case (max 170mm height) and my memory is 44mm tall.

Anyway, got some impressive results. All fans are set to get into 100% after 75c. Until 70c, even noctua fans arent going 100%. For most of the time, im getting under 70c on 8700K, same temperatures as h110i with 1800 rpm fans blasting 50db in my face.
Even with fans hitting 100% on noctua, and its just one fan, its barely audible.

I made some changes too:
1) I removed h110 that was as exaust top, and i sealed the top holes with paper, at least for now; primary reason was to keep dust and other debris from getting inside, second reason was to evaluate airflow, coming directly from intake fan; there is a imediate fan below pointing to the gpu;
2) Turned psu fan to silent mode (only runs if it hits some temp, i guess its 50c+, seasonic gold), and turned psu intake to bottom, so to also not interfere with airflow
3) Replaced crappy exaust fan with noctua AF12.

System is barely audible now, and even at P95 AVX, i was hitting max 85c. After a long time of realbench, which both heat up gpu and cpu, max cpu was doing 75c, so by all means a success.
I will confirm values when room temperatures goes beyond 30c, the last two days it was between 25 and 28c.

Max gpu temps are 69 (2+ since h110 replacement), under 67% max gpu fans.

So far, i consider it a success; much less noisy and with just one fan, that is really impressive.
Now i have some questions, feel free to send your opinions:

1) Considering i cant change the case right now, i can get any benefit putting some high quality noctua 120mm fan on front of D15? 2-4c would be good.
2) I couldnt find much case variety that allows 180mm+ clearance.
The options are either full towers on some midtowers with restricted airflow intake. Someone has any suggestion of good cases with massive airflow input and clearance? Extra bonus is possible to seal top, like fractal design.

Drive cages are a damn issue. The problem, at least for me, is that i dont want to give up on my HDDs, they have decent size and performance in RAID0. Most priority stuff i put on NVME, i still wants to replace all disks with SSDs however putting another nvme will probably choke the band on 1151 platform, and even sata ssds are still costly to replace several disks.

You will only see 1-2c difference with two fans. not worth it. I run 1.

I put my HDD in external closures so I don't have to hear them unless I need them. I now have just SSD and nvme in the case - a 960 Pro and two 1 TB EVO in Rais-0. Very quiet. Most of my data (photo images) are on external HDD - 6TB + 2 x 2 TB.

Results look good, and pretty much spot on with what you should expect from that change.

In addition to the EVOLV X, you may want to consider the Enthoo Pro M as an alternative. It will have the clearances you need, great airflow and construction, and not break the bank if you are budget conscious.

Yeah....the little girl hentai avatar is really creeping me out....
