primochill typhoon 3 question

[dmccart4]

I have a primochill typhoon 3 and was thinking of running two loops from it, 1/2"ID main loop for cpu and gpu and a small 3/8"ID just for cooling the chipset. Would I have problems with flow having 1/2" and 3/8" outs on the same reservoir?

I picked 3/8" tubing as it gets a bit messy around the cpu with all 1/2" tubing.

I'd be more worried about the failure rate of those things, they've got a bit of a reputation for cracking.
