I care less about temps, I just want efficiency and reliability, with quality, I got some Tt stuff way back when and was excited about it, when it got to my door I opened the package, the first thought to run through my mind was "This is utter complete sh*t garbage!" it never went into a system I threw it out did some more research and went custom, 3 years now and I have not reseated the blocks or any thing and I still get stable reasonable temps 100% lower then air cooled and hell of allot quieter!
I have not seen one even half descant thing from Tt I would consider worth spending money on, I grew up in heavy industry, and when it comes to parts cheap or flashy are never good. The block I ordered from Tt looked half ok, but upon seeing it in Real life I realized what a sh*t product they make, more of their stuff I see the worse I see it is.
I know of a block that is 20US that would wipe the floor with ANY Tt block, and even with out a rad a half as*ed DIY loop would wipe the floor with Tt, Koolance at least has a half appreciable product that is acceptable where as Tt does not.
