Question about 3pin to molex adapters and power

[Sacrifice]

I'm trying to power two h55 pumps (and a case fan) using a molex to 4x3 pin splitter.


Will each of the 3 pins be outputting the maximum power possible to the h55 pumps?

Or can anyone point me to some adapters that I can buy that will output the full voltage from molex to 3 pins?

Thanks!

Good question. I have two gpu's with h55's. The top one was always between 85-94 in Witcher 3/some other games, the bottom one at 60-75C. Today I swapped them around, the (new) top one was at 80C, the bottom one still went to 94 and started throttling.

So I'm not sure whether it's the pumps or what, because I reseated/reapplied thermal paste. And I'm not sure why the (now) bottom card is so much hotter than the top.

Did you swap the coolers or the cards?

One of the h55 could be faulty.

I think I'm going to swap the pumps tomorrow to see. I had swapped the cards
