Had an unused port that leaked light on the wall behind my TiVo, even though the port had built in dust flaps. This cap fit and blocked the light spill, as I hoped it would.
When your building your loop often time you want to run your lines right to the radiator, then realize there are no room for the fittings. Primochill to the rescue with their awesome extensions that are perfect fit and a 90 degree that swivels for all your needs.
They are good quality, the colors are consistent even after ordering them at different times and have had no problems with leaking.
I've been using this coolant for 6 months and will he draining it soon and refilling with the same thing. Temperatures have remained consistent and the color has looked great throughout. Just make sure to clean your loop well between each coolant change and everything should work great. I'm probably on my 6th coolant change on this loop. I've also used the VUE in this loop and that was pretty fun to have. With any coolant you do need to prep your loop properly to not have issues. So use care when using these coolants.
I will buy Primochill Opaque or Vue again!
I am so lucky these screws are identical to the ones in my red devil 6900 xt ultimate... I stripped the originals during a repaste and ruined my thermals but with these temps are the best I've ever had (after hydronaut paste applied)
