And you are getting that flow? In looking at the res in tbe pic, that waterline is perfectly flat...

is that a parallel or serial block on the gpus? The card that is getting hot might have a blockage in it, spraying yourself doesn't mean flow, it means there is pressure in the system, pressure can be indicative of a blocked block. I guess I should say abnormal pressure.

Yup I concur. Best to take it all apart and see.

Let me ask, which direction is the flow heading? Is the 2nd (bottom) GPU the first from the pump? If so, could be blockage.

Hope you cleaned all your gear and especially the rads prior to installation.

its going down to cpu then Gpu, iv took both blocks apart and cleaned. they weren't that bad.. re done my loop as now it goes res/pump > rad > cpu> gpu1> gpu2 rad > res/pump.. still the same results.. could it be a dead gpu?

Doubtful.. they don't get hotter like that... at least that i have seen. maybe its just a bad mount (yes, aware you mounted again).

Can you post links to the exact radiators you have? Are they hot to the touch too?
What fans are on them? What direction is the air moving through each?

First response was useless.
Second was probably as useless as the first.

Hopefully third edit is the charm...

I noticed that you have your block set up in a series circuit. I looked at the installation diagram of your SLI bridge. It seems that there should be a fitting to block the water flow in the channel on the right. Is there?

So you're running the GPUs in serial. That looks about right as the the GPUs are usually 5c-10c different from each other on average but your temps are way out there which makes me think from what I know now, a bad mount as ED said is very possible. Everything else looks fine but that temp on that GPU. I think you're going to need to remount that GPU is your best bet at this moment.
