I'm really new to vortech. I just picked up two gen2's and can onlyn currently run one, as I need a new wet side for one of them. Anyway, it seems to be getting pretty darn warm to the touch. Is this normal? I would expect some heat, but this seems a little suspicious. I can still touch it, no problem, but I'm wonder ing if I should be doing something differently. Since I purchased them used, and they were kinda neglected, I dont have a manual but I do know about aligning the sides and it runs with very little noise, it just has a little electrical whirring sound. Oh, and I set the pins to the appropriate glass thickness. I just want to know if the heat is normal. Thank you for your help
