Got 2 more GekkoScience 2PAC usb miners from Ebay. They are running at about 10.5 GH/s and 90°F each. It is kinda hot for me. I should get my USB fan today and see how much cooler I can run them.
Also earlier I was running all 3 sticks side by side and the heat shut down one stick.
I will also start tweaking gekko frequencies through cgminer or on the hardware to test faster speed and how robust my USB hub is.
I decided to run the miner on thecoin.pw pool - so far I am happy with the results - getting about 25 GH/s on the pool.
