I was only running flammable denatured alcohol today for a short while. I soon removed it and decided the real problem was the block.

It came with the Swiftech h20-220 Ultima Extreme kit, but it is designed for a low volume system.... certainly not with a 3 gallon per minute pump.

I did a lot of stuff today and took quite a few pictures which I'll try to get to tonight. I opened up the block, removed the inner o-ring, drilled out the inlet hole to match the size of the outlet, and cut 4 grooves in it to allow more water and it worked like a charm.

Now if the Chiller isn't full the return coolant shoots right through the evaporator which is about 3 inches from the side of the cooler on that end.

I'm pretty psyched to see what it's like in the morning when starting @ -45 Celsius.

Definitely better already and my pump no longer sounds like it may die soon.

EDIT: I just realized I have been mis-spelling Celsius for awhile now.

Be back soon with some pictures.

-20 Celsius and the flow is about half of what you saw in the picture. Can't really tell by the feel when your hand is submerged in -20 coolant....but I can tell just the same. The pump, however, is still quiet and cool so it's not working hard. May have to cut 4 more grooves in the block soon.

I could thin it with some water perhaps.....it is ~ half anti-freeze and half washer fluid.

I guess the flow isn't so bad yet.....

And here is some more pictures showing my new hose configuration and my beautiful new hose insulation. $1.33 for 6' you cant beat that and it's self adhesive, but I wrapped in with black tape.

And for kicks a picture of taking extreme measures DO NOT TRY THAT.......

Going to try for 5GHz again in the morning when it's very cold.
