MMKGraphx Posted November 24, 2021 Share Posted November 24, 2021 System: AMD R9 5950x, MSI X570i Pro WiFi, Corsair Vengeance RGB Pro SL 2 x 16gb, Sabrent Rocket4 1 TB NVMe4; Sabrent Rocket Q 1TB NVMe3; GByte RTX2070 Super XD3 PumpRes Combo XC5 Cooling Block AMD XR5 Radiator 240mm XL5 Coolant Hydro-X Soft Tube 10/13 Crystal 240 Case; 2 x LL120 Rad Fans; 1 x LL120 Intake Fan; 1 x LL140 Intake fan; Current flow direction is PumpRes --> CPU Block --> Radiator --> Pump Res unfortunately, I routinely get coolant temps around 49c under load . Is this normal? The delta seems really high considering its 19c ambient 48c Coolant delta of 29C. The coolant temp sensor is mounted at the bottom of the XD3 PumpRes.

LeDoyen Posted November 24, 2021 Share Posted November 24, 2021 depends on what case you installed it, if it has decent airflow, and if the pump isn't running crazy slow. A 240mm rad should be enough to take care of a 5950. That said, it may not be enough if the rad is set as exhaust and the aircooled GPU dumps its heat into it. You may have 19 ambient temperature, but 40° case temperature, which would be the minimal temp your water can reach, just as an example. Link to comment Share on other sites More sharing options...
MMKGraphx Posted November 24, 2021 Author Share Posted November 24, 2021 Case temp is usually a little above ambient 26C idle 38c under load. But now that you mention it, the back half of my Graphics card sits directly under the pump and 12 mm away from the sensor. Likely the sensor is being heated from below as well as the internal coolant temp. I think I'm going to install a coolant temp sensor up near the rad. Corsair said the configuration in my case was not possible using the cooling config tool. It is possible without case mods but it makes the tolerances quite close. I'll post some photos to demonstrate and maybe someone can suggest something I have not considered. Not a lot of options for more fans but there are some possibilities.

LeDoyen Posted November 24, 2021 Share Posted November 24, 2021 yep, by all means, send pictures 🙂 it looks like an airflow issue but it's hard to guess as is. Link to comment Share on other sites More sharing options...
MMKGraphx Posted November 24, 2021 Author Share Posted November 24, 2021 Small case big cooler components. Not a lot of extra room Link to comment Share on other sites More sharing options...
MMKGraphx Posted November 24, 2021 Author Share Posted November 24, 2021 no room to move the radiator due to size of the graphics card. Fan space at the bottom but dont want to try to exhaust from there. Intake might make more sense but I'd need a a couple low profile 140's blowing into the graphics car and a little around the edges. Rad fans are push exhaust out the top hoping to get additional heat convection moving the air that way. Unfortunately, there is so little space that I'm not sure it would make a difference.

MMKGraphx Posted November 24, 2021 Author Share Posted November 24, 2021 BTW fist custom loop so go easy on me fellas. Link to comment Share on other sites More sharing options...
LeDoyen Posted November 24, 2021 Share Posted November 24, 2021 ah a 280x. Often the problem is the top glass blocking the airflow too much. You can test that by removing it and seeing what temps you have without it. If you have the top filter on you have to remove it too, there is no point in filtering air going out and it will get rid of one more restriction. Other users have custom loops in it with decent results so it's worth looking for it in the forum to see what their airflow setup is. I think it may often be using top intake, but not sure 🙂 Link to comment Share on other sites More sharing options...
magarity Posted November 24, 2021 Share Posted November 24, 2021 That looks like a 280 case not a 240. Go to the hardware store (Ace, HomeDepot, etc) and get some little rubber grommets to raise the top glass about quarter inch. Or you can 3d print some. This will make a huge difference. Also consider a pair of 120 fans in the bottom as additional intake. Where's the drain port? Link to comment Share on other sites More sharing options...
MMKGraphx Posted November 25, 2021 Author Share Posted November 25, 2021 Yeah there is no 240 I just mistyped. No place to put drain port. I just pull out the graphics card and drop the coolant sensor plug. Drains fine OK so thanks a ton guys. Pulled the top filter and elevated the glass 7 mm. Added a 140mm LL to the bottom as intake. Coolant temp dropped 10 c. under 90% load. Wow good call Link to comment Share on other sites More sharing options...
MMKGraphx Posted November 25, 2021 Author Share Posted November 25, 2021 Should note also the idle temp dropped almost 9c as well 36c to 27c. with the cooling pump working half as hard.. very nice, and a sincere thanks Magarity and LeDoyen for the spot on tips.

magarity Posted November 25, 2021 Share Posted November 25, 2021 Hey you're welcome; now repeat after me: "I like my 280x because it's so small and I dislike my 280x because it's so small." Link to comment Share on other sites More sharing options...
MMKGraphx Posted November 27, 2021 Author Share Posted November 27, 2021 Exactly True 😆. Love the aesthetics, beefy construction etc. ....but boy jamming everything in there is a challenge. I will be adding a T and a drain valve now that I have things a bit more temp friendly. Next iteration. Money doesn't grow on trees. Link to comment Share on other sites More sharing options...
