I have a question here that I've kinda been pulling my hair out for, so first of all to understand my predicament, let me just tell you that Ebay and Amazon don't deliver in my country but I can get Aliexpress products delivered just fine. I'm building an i9 9900k PC with a 2080 Ti that I won't be overclocking (CPU or GPU) I want to go the air-cooling route but the problem is that Dark Pro or Be quiet or Noctua or any other mainstream air-cooling fan brands aren't available in my country, only Cooler Master is available. The most expensive Air Cooler that's available is the Cooler Master MasterAIR 620P. I was thinking of doing a couple of modifications to it to get good temps that you'd generally get with on an i9 9900k with a Noctua NH D-15. For starters, I was thinking that I'd replace the stock fans that the Master Air 620P comes with and put on some High RPM DC 12v Computer Server Fans or Corsair SP120/ML120 fans which are static pressure fans (I'll be testing both of them on the cooler to see which ones produce better temps and I'll be putting on 3 of them, the cooler only comes with 2 fans, so I'm betting that putting on 3 fans as opposed to 2 which are better than the stock fans will produce better temperature results.) In all the benchmarks that I've seen online, the NH-D15 has performed better than the Cooler Master MasterAIR 620p and managed to provide an extra 7c - 10c of cooling. I've provided ALL the benchmarks that I saw at the end of the post: (You don't need to read them, the only difference between cooling provided by MA620P and Noctua NH D-15 is a difference of 10c ONLY.) Now physically comparing the coolers: All three coolers come with 6 heatpipes. MasterAIR 620P's Heatsink weight without fan = 850g Noctua NH D-15's Heatsink weight without fan = 980g Noctua's D14 Heatsink weight without fan = 900g So Noctua's NH D-15 Heatsink is only 130g heavier than MasterAIR 620P. And Noctua's D14 Heatsink is only 50g heavier than MasterAIR 620P. I also watched a video by a youtuber where he used an i9 7900X paired with Coolermaster 212X and got 79c temps at 4ghz under an Aida64 Stress Test for 40 minutes. And Coolermaster 212X cooler weighs a mere 492g, which is less than all the coolers mentioned here. Now the i9 7900x is a 10 core 20 threads processor as opposed to the i9 9900k which is an 8 core 16 threads processor. Now looking at the CFM numbers listed on the cooler's pages: (The numbers listed on Noctua's website were cubic meter per hour so I converted them to cubic feet per minute using google.) MasterAIR 620P CFM = 53.4 Noctua NH D-15 CFM = 67.6864 Noctua D14 CFM = 64.920129 Statistically speaking I think I'll be able to achieve the 65-67 CFM number by putting on any of the fans I mentioned above on the MasterAIR 620P cooler. So do you guys think that the MasterAIR 620p cooler after these fan modifications will get some results very close to Noctua's NH D-15 and be able to support the CPU under 4k gaming load? and 1080p video editing/rendering? P.S, Now I know that some of you are gonna suggest going with an AIO, I hate AIOs, I prefer air-cooling over liquid, I HAVE to go with air-cooling, AIOs are not an option. Also, some of you might also suggest just buying a Noctua NH D15 Cooler from Aliexpress but the problem is that it being sold by 2 or 3 suppliers and neither listed product has a single review, so it might just be a cheap knockoff that doesn't produce any good results, so I'm going for a locally bought OEM product and doing fan mods on it instead. P.S, I've attached all the Benchmarks that I saw.

Cooler Master bills the MasterAir MA620P as compatible with Asus Aura Sync. Can anybody help me figure out how to actually make them work together? I have a B450-F Strix motherboard with a pair of 4-pin RGB headers. The logical (indeed the only) way that I can see to connect the cooler to the board is to hook the included 4-pin Y splitter from the fans to one of those RGB headers, but when I do that the fan lights don't come on at all. The Aura app lets you change the colors for each RGB header individually so I tried cycling through various options for the header the cooler is connected to, but none of them yielded any result. I know the lights on the cooler fans DO work and I didn't just receive a pair of defective fans, because if I connect them to the controller Cooler Master includes (which itself connects to a MOLEX) then the fan lights come on immediately and I can cycle through the colors/patterns using that in-line controller. What am I doing wrong here? Is the Aura Sync compatibility with the MA620P less than Cooler Master is billing it to be? Or is this a problem with Aura, which is by all reports a notoriously buggy piece of software?
