yopp<p>So, after few attempts my first ever water cooling loop is up and running without leaks! </p><p>It took just three attemps to fit all the tubes and one attempt to unscrew the flow sensor that I tighten with a bit of “Liquid Teflon”, which is so good, that it basically glues threads together and they are impossibly to unscrew. It took A LOT of brute force to detach it from tank cap, with a bit of cosmetic damage. So much for “easy disassembly” that label advertises. </p><p>Surprisingly loop does it job very well and even under quite a high load GPU’s stay in 25-30°C range. Next week I’ll try to crunch some numbers and we’ll see how it well it can keep temp down under long sustained load. </p><p>2 things left: write esp32 firmware to spit flow and water temp readings to usb serial and find a way to control fans pwm, to adjust only pump and radiator fans speed. </p><p>First one is trivial, but pwm stuff is not. I have backup option of managing fan profile using Redfish HTTP API abusing Fan Profiles. But I rather find a way to read and write actual pwm duty values, if it’s even possible. </p><p> <a href="https://feed.yopp.me/tags/custombuild" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>custombuild</span></a> <a href="https://feed.yopp.me/tags/watercooling" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>watercooling</span></a> <a href="https://feed.yopp.me/tags/diy" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>diy</span></a> <a href="https://feed.yopp.me/tags/homeserver" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>homeserver</span></a> <a href="https://feed.yopp.me/tags/selfhosting" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>selfhosting</span></a></p>
