Coasterman. Deal with what you bought. It don't let the smoke out, your overclock is okay, your temps are okay. Replace it as you can.
You bought at the start something we know in the WC world as a piece of %^&% and when you can replace it, do so.
What some are saying is trash the full WC loop (except the new rad you bought) and get a quality air cooled HS till you can afford a real WC loop.
BTW, in 6 months your pretty new rad will probably be funked up due to the aluminum in the original TT WC loop. maybe before a pump gives up or the top of the CPU block decides to crack.
Your problem, part of the hobby. Thank goodness I spent THREE months learning before I bought ONE WC part.
You didn't, best of luck.
