Wasn't sure where to park this thread, but I'm curious to hear what others think of what I've learned in the last couple days as I benchmark my new system.
Hardware details up front: not-yet-overlocked 9990K processor and a 2080Ti, D5 pump feeding the loop that has 2x560mm rads with 8x140mm fans (push only).
Inline sensors: 2 water temps, one before the rads and one after, later installed 4 more thermometer based ones to capture exhaust air temps at mid points on the rads' exhaust paths. These are all tied into an Aquaero 6 who's aquasuite software has been instrumental in testing the factors below.
I was expecting to see the water temp drop a couple degrees between the two water sensors but no, its much much greater. Initially I had a 6c delta under load between the two but over time I tweaked the pump speed down and kept the fans running as close to 400-800rpm as I could while aiming to keep the post-rad sensor's readings as close to ambient air temp as possible. I've aimed to keep the pump at its slowest setting of 800rpm as I adjusted the slopes. The four air temp sensors let me see how much more room I've got by showing me four data points of temperature as the water passes through the radiators and if the last one is a very small difference that gave me confidence to dial things back even more.
I got an 18c delta by the end of this process. Water coming in to the radiators at ~41-43c and leaving at ~23-25c. Wow. Just wow. The GPU gets to about 56c under these conditions and the CPU hovers around 65-70c and the whole thing is so quiet. Its just weird to feel the temp difference between the tube heading to the CPU vs the one coming out of the GPU.
I've always seen people talking about medium/high pump speeds to keep component temps down but far as I'm concerned both of the components are well within their tolerance. What I am contemplating though is replacing the tube between the GPU and the rads, its PETG and my understanding is around 60c would get to where it'd slowly deform. Changing it to even just Acrylic would give a lot more head room in case something goes side ways.
Anyone else play around with their settings with this as a goal over component temps? I was not expecting these results at all. Really cool stuff.
