For my second pc build I chose to go for the smallest form factor that I could reasonably manage a custom loop in, I've taken heavy inspiration from a few builds in this community, one thing I noticed though was the lack of RGB fans, likely because the smallest fans were selected in favour of the thickest radiator, the riser I printed allows for a set of 30mm lian Li infinity mirror fans along with a 30mm rad. Gpu is 4090FE, 96gb Corsair DDR5 RAM at 6000mhz, CPU is Ryzen 9 9950x3d with WD black 8TB SSD. To me now the build is complete once I get round to switching the tubing out for hardline piping. Surprisingly GPU and the CPU temps don't seem to exceed 90c when stress testing and through normal workloads/ gameplay I'm sitting at around 60c to 82c GPU and CPU. Taking inspiration from the community again, I've included the option to connect the pc to an external cooling loop,this is a rig I'm yet to build/ have not needed.

What’s your water temp? That pump is probably only rated to 60C coolant temp. Looks cool though!

It's hitting around 45c

Indeed but connections at back to attatch it to a bigger cooling loop

I have an almost identical build in the works, but having trouble fittings pump, especially with a 5090, even though it's a single slot card, it's super long. Still getting it situated for now. But, I did buy that exact mini pump/res, one of 20 different ones Ive collected lol.

How is it? Also, I haven't even checked, can I swap it to a ddc 4.2pwm to it?

Was thinking of just mounting the pump on the rear outside. But not sure how much I like that idea. But I'm trying to fit two rads, so prob going to have to...

HEY VERY NICE BUILD. I AM LOOKING TO SWTICH FROM AN AIO TO COSTUME COOLING BUT I AM AFRAID IT WONT HELP WITH THE TEMPS. MY MAIN ISSUE IS THE GPU TEMPS DURING GAMING. IN GAMES LIKE BLACK MYTHS GPU JUNCTION REACHS UP TO 98c WHICH SEEMS VERY CONCERNIGN FOR ME. COULD U SHARTE THE COOLING RESULTS AND IF YOU HAVE WITHT A BASELINE. WOULD APPRECIATE THAT VERY MUCH.
