New H150i RGB PRO XT installed on stock 10700k and getting 55c-60c idle temps, then instant 95c+ temps when do anything.
Thought it might be a bad mount, so redid mount. (ended up remounting 4 times) same results. Tried different orientations of radiator, ran pump with jumpered psu to check to see if pump working. Can hear pump noise.
Went and bought another H150i RGB PRO XT and installed using the mounting gear already installed and have temps of 28c idle and never over 65c when doing anything.
The original unit looks like it is faulty. So I assume an RMA is in order.
As it was purchased from a Ebay store, i hope it is not a huge hassle to return.
