Watercooled GPU overheating

[Kasei Vallis]

I recently built a PC and aspired to a quiet, water cooled system. After a few weeks, it was time to convert my R9 290 to water cooled and I completed that last night. Problem is, it does not seem like the pump is working as the GPU quickly goes from 45c to 90c before shutting off.

I have tried adjusting the bios settings for the fan from Normal to Full, with no effect. I have not pulled the GPU out yet to check seating but it made contact with the cooler.

My specs
Thermaltake Suppressor F31
EVGA 750 GQ PSU
GIGABYTE GA-Z170X-Gaming 7
Intel Core i7-6700K
GeIL EVO POTENZA 16GB (2 x 8GB)
Thermaltake Water 3.0 Riing RGB 240 attached to the CPU (Pump on CPU_FAN, fan controller on CPU_OPT)
SAMSUNG 960 EVO M.2 250GB
SAMSUNG 850 EVO 2.5" 500GB
Seagate FireCuda Gaming SSHD 2TB

Here's what I went with for the Sapphire 290 4GB
Kraken G10
Corsair H55 (GPU was cleaned with isopropyl rubs and new arctic silver was applied)
GELID VRM Cooling (Pump connected to SYS_FAN1, G10 Fan to SYS_FAN2, Radiator fan to SYS_FAN3)

I have two 120mm fans in the case that had to be disconnected to get the new fans powered. I am going to get a splitter for those.

I may have resolved this. My power settings for the SYS_FAN1 settings were set to the defaults. I raised the power curve in SIV and the pump seems to be working now.

■ reinstate GPU original air cooler, see if the temp also high, that is to figure out Kraken G10 and Hydro H55 were not fail.
■ test Hydro H55 on CPU..
■ try SATA to 3 pin adapter or 4 pin molex/peripheral to 3 pin.
