Screws? SCREWS? Don't ...
I am looking at metals in the cooling loop. Rad Copper/Brass. Sensors Brass. CPU Block Nickel. Pump??? Reservoir POM+PMMA.
What material in the pump is in contact with water? I asked the mfg. but, so far, no answer.
I don't think nickel in the CPU block is a problem.
I received an answer, or, a statement from ThermalTake Technology:

The only information we have in regards to your inquiry is a lightweight POM and PMMA construction. As far as the pump goes, we know that any metal that comes into contact should not rust or deteriorate as long as the system is routinely maintenanced.

That is about what you would expect for an answer. Most likely your pump is Arcylis / POM and polished stainless steel. Unless you buy cheap from China then it becomes a crapshoot and hard to say what you get.
silver has an electro negativity of 1.93, nickle is 1.91, copper is 1.90, brass is 1.92-1.93 and aluminum is 1.61. you need a difference of ~0.25-0.3 to have galvanic corrosion so this is not anything about silver and nickle not getting along (silver and copper are further apart, and copper and brass are about the same apart.) the only reason that they have this is to void warranties, and to get people to buy their BS fluid that will clog blocks and is highly profitable.
Not sure if anyones said it yet I only read OP. UT60 isn't the rad choice for what you want. It's low fin density and thick = good for low speed fans, won't benefit much from push pull. Get thicker fin density and sacrifice some thickness in the rad potentially for that kind of setup.
