Hose/bard/thread change

Need a little help

Basically I'm going water cooling by the end of the month and I have all ½ ID tubing stuff. I haven’t bought the hose yet as I'm away from home for a week. I was thinking of using smaller hose as my case is quite cramped already as I have four HDD and three 5 ¼ bays already in use. I really do not want to modd my case.

If I do use smaller tubing/hose say 3/8 thread will there be a massive performance difference.

The stuff I have so far:

1/2" TDX Athlon64
Laing 12V-D5 Pump
1/2" XSPC R120-D
Danger Den Single Bay
Swiftech MCB120 "Radbox"

7/16 is optimal, not sure if it will work on that block but it should as it fits snugly over 1/2 barbs.
If you have a 'push fit' type connector get some of these:

That'll convert the block's current fittings down to match your 10/8 tubing.

7/16ths works fine on tdx's, you just need to sit the end of the tube in a mug of (very) hot water for a couple of minutes before it goes on.

As far as going to a drastically smaller size goes, youre buggered if you want to use that pump, as the barbs arent replaceable
