* - From this point forward the "Load" temps seemed to go down during testing, the "Max" temps were 46.88c but the temps were in the 45's during load.
** - Same here...
*** - Limit is here for these...also I stopped after 3 for 240 and 2 for higher.
**** - Limit again...
Summary
To summarize here it seems like diminishing returns come fast above 240mm with custom water coolers and large radiators but with smaller ones (great for smaller cases where they need to be spread out) they tend to be useful with up to 4 120mm radiators and 2 x 120mm rads are bettter than 1 x 240mm of the same type so this can be used to min/max things when doing high-end overclocking in limited space. Also, these are the numbers for a stock 3950x but I plan to add some OC numbers that can be linked to this info (Such as whether the diminishing returns after a certain amount of radiators changes with more heat from an OC) and whether adding video cards and such impact max OC or temp numbers...I don't think they do for GPU's but you never know. I would imagine with the bigger CPU's like the 3990x these numbers change a lot and maybe more radiators see increased utility but I've yet to try anything less than the maximum radiators that can be fit in the ENYO for my extreme OC attempts. I was gathering this info for myself and figured I'd throw it on here in case anyone needs it. Let me know if you guys want any additional data...thanks!

Forgot. The +CFM to -c values apply to ~100W CPUs(95W-105W). So lower TDP chips(65W) will see a greater effect and higher TDP chips (127W to 280W) will be anywhere from a a little less effective to a lot less. Many GPUs already have fairly decent air coolers, but if you really want to push them you need a lot of CFM in custom cooling due to greatly increased power draw.

Takeaway:

Air/AIO: +20CFM = -2c (1+ CFM = -0.1c)

Custom: +20CFM = -3c (1.5x better per CFM)

OCing = more power = more cooling. Higher TDP chips(9900KS, 3990x) will need more cooling to OC or even run. Lower TDP chips(65W Ryzen) need less but if you OC then you need more as they use more power.

Water cooled GPUs(1070 and up) have higher TDP(1070 150W, 1080 180W, 1080 Ti/2080 Ti 250W, 3080 320W, 3080 Ti/3090 350W, Vega 56 210W, Vega 64 295W, 5700XT 225W, 6800XT 300W/6900XT 300W) and need more OCing them as they will use a lot more power than stock.

It's harder to push a CPU and doesn't change 3D Mark scores as much as GPUs, so it's best to passively cool a fast CPU with little to no OC and put all the CFM you can on the GPUs.

irl, AIO are better than an air coolers with equal CFM(varies with heat sink surface area) and about the same as a custom loop with similar CFM(and heat sink). Fans with higher static pressure would also make a difference besides just pure airflow.

Thank you for writing this down and putting it out there!

As for if adding a GPU to the loop effects the CPU, I can almost garentee that this is the case. I tested it really quickly the other day, I had the 9900K and two 2080 Ti's in the same loop with two 240 rads and I wasnt able to do any overclocking at all because my CPU was running too hot. I then removed one of the GPU's and was able to overclock the CPU just fine. And even with one GPU in the loop it felt like the CPU was taking a hit in terms of thermals, as without any OC it was running idle at around 51 degrees and it was hitting around 78 degrees under load. I did manage to do a little bit of OC but not a whole lot as you can imagine.

Hope this information was usefull in some way, I look forward to see what your findings are! And if you already knew all of this feel free to tell me and I will remove this comment :)

Excellent cheers this helps plug the guide gap.

I'm building my first PC using the ENYO case, so anything like this is really helpful. Thanks.:steamhappy:
