Sativa

@r3loAded Okay, today the X42 and the Z370-I arrived, i made a few test fits in the UMX3 and experienced some issues. First of all, i had to rotate the Pump because it would block of both RAM slots. I know, the NZXT Logo is now sideways, but i think i just wont light it up. Next, the Radiator + Fan didn't fit because the CPU Power connector on the MoBo was interfering. SO i took a saw and a file and took one of the Corners of the fan of and voila, it fits. Its really close, i have like 1mm left for Rad+Fan. I still have to wait a few days for the 8700k to arrive until i can finish the build.

@r3loAded Thank you very much. I still am unsure about interference with the Mainboard because of the Top heatspreader, but i guess i just have to try it out. I will create a Build on PCPP as soon as i have all the Hardware.

@Bananasplit_00 You are totally right about the Chroma thing. It makes them look way better. But those top plates for the heatsink adds another 6mm, plus DH15S height, im over my max height limit (6mm + 160mm) i need to stay below 163mm.

@r3loAded Thanks, the preinstalled fan on the X42 is 26mm. When im at home im gonna try to measure the exact amount of space i have, it wont be that easy because i dont have a motherboard to put in the case yet. About the position where i'd put the 140mm rad, if you take a look at the picture, the 140mm fan goes to the top, the 120mm to the back.

@EvoKnvl Yeah i already thought about the D15/D15S, The D15S may fit, but its kinda ugly imo. I don't really like the standart silver from the fins. @Bananasplit_00 Cryorig H7 is a okay option, i will think about it when i decide. @r3loAded Do you have some information on the Cooling performance for the Kraken X42? I really like the esthetics. Someone maybe has the X42 and can take a measurement of the width of Rad + Fan? I need to make sure it fits. What do you guys think about the beQuiet Dark Rock TF? I think it will look superb with a RGB Fan as replacement, but i am unsure about the cooling performance. I know the DRP3 would be better in cooling performance and probably noise wise, but i can't be sure if it will fit with my TridenZ Memory without lifting the Fan, which i wont be able to.

@JobbelsNL Sadly i don't have space for a double Radiator anywhere, like i said, i have support for 1x120 and 1x140. I thought about x42 but i am afraid it wont fit.

I'm searching since weeks for the perfect CPU Cooling Solution. I'm going to build an i7 8700k on an Asus STRIX Z370-I Motherboard. I'm going to use the UMX3 by Jonsbo/Cooltek, so i have a limited Cooler height of 163mm. Also, it's the Windowed Version, so i would prefer something that looks nice. I will need a good amount of clearance for G.Skill Trident Z Memory (44mm). The UMX3 Case only has support for 1x120 and 1x140 mm fan, i could easily install a 120mm AiO, but as i've seen, those really can't hold up to most Air Coolers like the (cheap but nice) 212 EVO, so I don't really want to do that. I thought about using a 140 AiO because those are atleast able to outperform some of the Aircoolers and they look really nice (thinking about NZXTs X42). Sadly i am really limited by the Radiator + Fan size, they can't be more than ~55 mm. Please help me find a Silent, Cool, Nice looking CPU cooler. Air/Water i don't really care. Money won't be much of an limit. (Also i am planning to Overclock the CPU in the near future, but that won't be a top priority) I've added a picture of the Case from the manufacturer site.
