Apogee GTZ

[Martinm210]

Would be great if you drop pressure test it so that it can be added to the flow rate estimator. It's the only thing holding me from buying one. As we know it will perform side to side to the Fuzion and EK, pressure drop is an important factor.

I can't figure how to extrapolate your quick measurments you just posted, sadely, except it is a lot far more restrictive than a Fuzion and quiet a bit less than an EK supreme

An easy estimation would be to put the supreme curve in get a number, then put the fuzion v2 in, get a number and split the difference. That'll be close enough until I get the thing pressure drop tested.

Unfortunately because I'm using my king flow meter for the CPU thermal testing loop, that puts me down a flow meter to do any pressure drop testing.

Anyhow these are my recommedations with the GTZ. Make sure you use the stock backplate (yes that means a motherboard removal) and also make sure you tighting the mounting screws ALL the way down. A little oil on the screws will help with this, but it's important that you use the stock backplate and mount with maximum pressure. The mounting mechanism included is critially important to maximum efficiency.

I can confirm that too. Even when using the EK springs cranked down 8 full turns, and the backing plate, I still got a performance increase from using the GTZ mount. That mounting mech. really clamps the block down.

Why would you if you are using the same block each time? The mount is essentially the same, in operation, as the EK or D-Tek backplate, both of which also require removing the motherboard for initial installation of the backplate.

Thereafter, changing cpu's requires no removal of the motherboard, provided you are going to use the same block.

Not really. You stick the back plate on the back of the mobo. If the back plate move or fall down, you need to remove the mobo ... And the back plate will not stick well if you change the mobo.

If you change motherboards and cpu like you change diapers, then it's a wise idea to cut the cpu area on the motherboard tray so you can access it without removing the motherboard.

Quite true.......

But if you are using one mb consistently with various cpus, as I have done with my D-Tek, the sticky won't let go and fall down behind the motherboard all of the sudden. In fact, quite the opposite....it'll stay stuck until you remove it. And this is after half a dozen cpus have been through my motherboard and over a couple of dozen mounts of the D-Tek.

And if you have to change mb's, just by some double sided sticky foam tape...they do sell such an animal...and replace what was used on the first install.

Coolermaster have this system on their new case. I find this is a good idea.
On the mozart tx, it is not possible because I have the psu behind the mobo
I don't undestand why the screws are not fixed to the backplate at first

Yes, I saw a couple of degrees, mounts were all over the place without the stock backplate some very bad.

Since the stock mounting mechanism bottoms the screws out, it ensures the block is perfectly straight and that you've mounted with enough pressure.

I would also highly recommend using a large phillips screwdrive to tighten the mounting screws down. It's alot of pressure and not easy by hand, but once you put a screwdriver to use (better yet two of them), the installation is really easy.

While I've never really like mounts that require MB removal, it's worth it on this. Just use the sticky back or some other means to stick the backplate in place and you can remove as needed later without MB removal.
