OK so I have got myself a Silverstone Tundra TD3 water pump and replaced my faulty pump.

Unfortunately it is not much better than the cheap Cooler Master Seidon 120 that I've tried a few days ago...


Both could solve my problem, partially.  With the replacement pump I can now mine with all 16 cores, but only if set to Power Step 6.  many chips shuts as soon as I step up to Power Step 7.  Probably the pump is not strong enough to remove the heat???

The pump speed only reads 1200 RPM for TD3, while it's ~1000 RPM for Seidon 120.  Noticed that the original cointerra pumps are 3000 RPM ...


Any idea on how I could boost the replacement pumps so that I could fully utilize my miner to Step 9 again?  Maybe Liquid Pro could help?  I am using Artic Silver 5 for thermal paste now.
