Asus Maximus V Formula Fusion Thermo

Does anyone know what the internal of this block is made of?

I'm hearing stories that it's made with aluminum, and then some are saying it's made with copper

It's a copper tube and the heatsink itself is probably aluminum. Since water is not coming into contact with the aluminum there is no need for concern. How affective it is another story, Asus claims up to a 20c drop in temps. I like the idea, but keep in mind the barbs are 3/8".

Thanks utnorris, I'm gonna try it with and without water to see what I get for temps.

^^ good to know the difference between stock aircooler and stock water!

I remember on the old Maximus 775 boards it actually did quite well. I imagine since 1155 is not overly hot in the first place it should keep the VRM's in the 30-40c range depending on your ambients, but I am just guestimating that.

3/8 is fine. The days of massive impacts in having 1/2 are pretty much gone. Furthermore if you're the type that's anal enough to care about the difference you're going to be running multiple loops anyways.

Not really fine if you already have $150+ worth of compressions in your system.

I really hope they used the common G1/4 thread on this block, I have a feeling they didn't

My point is just what Paulbagz stated, make sure your fittings match up, otherwise you will have a mismatch, not that it would matter, but it wouldn't look right.

not a problem with 3/8 id tubing IMHO. one can just use 2 pieces of tubbing with _own_ OD with 3/8 id...

[Waterlogged]

Just a thought but. . .the barbs may be 3/8" but the I.D. of the tubing looks a whole lot smaller (maybe 5/16" or 1/4"?) and the barbs don't look like they are removable/changeable.

[Utnorris]

Barbs are not removable and the inner diameter is probably not as big as 3/8" tubing. But it's a good concept that proved itself in the old 775 days. It would have been nice if it had had a G1/4" hole, but that would have required a much different design than what is shown. Remember, there are actually two copper pies under there, one for water and one for the heatpipe.

those 3/8OD barbs feels innadequate.. they should've used G1/4 threads instead of using factory-made barbs.

[Church]

In addition to universality and a bit cheaper manufacturing imho G1/4 threads would be better also look wise, especially if board used only with air cooling. (=instead of those non-removable barbs that dissonate with looks two black stop fittings (with optional asus logos) imho would look much better).

[Merman]

I was just looking at the Swiftech 3/8" standard barb, as their page has the engineering drawings, and the inside diameter is .3" or 7mm.

The ID is very small, but honestly I feel the benefit of cooling the VRM with their Fusion solution outweighs the reduction in flow rate.
