kg135035 Posted March 22, 2013 Share Posted March 22, 2013 Hello I have an H80 with 2 rad fans, cooling node, and lighting node. I downloaded the new Link s/w when it was released. Most things were working well and some definate improvements were made. Except LEDs and my 2 fans will not vary with CPU temp when grouped with my i5 temp. But I think this is an issue that is being looked at so I just set up various speed profiles for gaming, night time, etc. and select them based on my need. The Link commander F/W is 2.0.6. Cooling node F/W is 1.2.5. Lighting node F/W is 1.1.9. H80 is 1.1.12 About 4 days ago, the link software shows the "H80 Pump" as 0 rpm and flashing red on the graphic. This would occasionally happen with previous link version 2.2 but it would resolve itself and be working fine in a few hours, maybe next day. So far, the condition has not changed and I am concerned my H80 pump is not moving any coolant. My BIOS reports CPU fan as 0 rpm. I confirmed the H80 pump is plugged into a molex power connector. I also confirmed the small 1-wire connector from the H80 block is connected to my motherboards' CPU fan header. I plugged my old CPU cooler fan into the molex (which H80 was using) and plugged the old fan's small connector to the CPU fan header. Old cooler fan runs fine and RPMs show up in BIOS. This confirms nothing is wrong with my power or fan header. Has anyone else seen this? Is my H80 broken? Should I be worried about continued use without my H80 pump running? CPU temp looks to be quite normal but I am thinking i may want to go back to my old cooling solution if this problems continues. Any advise would be greatly appreciated. Thanks K.

Toasted Posted March 23, 2013 Share Posted March 23, 2013 Make sure the L.E.Ds and fans are goruped to the CPU temp. Its better if you leave the fans grouped to the H80 temp as the fans will run louder than necessary when grouped to the CPU temp. Are the L.E.D.s on the H80 lit?

kg135035 Posted March 23, 2013 Author Share Posted March 23, 2013 Hello Toasted I have since changed the LED and fans to the H80 Temp group. Seems to be working better. But I still have to open any profile then switch back to a profile I want to use at the time. Then the LED and fans start to work as expected. As for the H80 pump issue. It is still showing red and is at 0 rpm. The white LED (the little man symbol) on the H80 block is lit up. Regards Kevin Link to comment Share on other sites More sharing options...
Toasted Posted March 24, 2013 Share Posted March 24, 2013 It sounds like the 1-wire to 3-pin is faulty. If the CPU temps are fine. I'd say the pump is running fine. If you would like the H80 cooler to be replaced you are free to submit an RMA. Link to comment Share on other sites More sharing options...
kg135035 Posted March 26, 2013 Author Share Posted March 26, 2013 Ok. Thanks for the update. I have put in the RMA. Regards K. Garner Link to comment Share on other sites More sharing options...
