Mini Test Report: Detroit Thermo D5 Top

Just Bought to two of these @ eBay yesterday and they are already shipped to me :D
Will be going to my CPU loop and GPU loop.

I enjoyed communicating back and forth with DetroitAC and shipping was always quick. (I'm a hop, skip and a jump away though).

Agreed. The package came promptly, and was packed very professionally. When I requested instructions (I know, picky picky...probably could have done it without them), he responded within an hour. I'll (hopefully) be installing mine tomorrow, but I haven't heard back on how likely it will be to re-use my existing o-ring yet. I don't have any CPU air cooling around, and don't want to be without a rig while I wait for a new ring to come. My pump is only about a month old, but I don't know if that necessarily means anything.

I did not use the stock o-ring. If you look at the inside of the top, you should see a lubricated o-ring already seated in the o-ring cavity surrounding the spot where you place the motor and impeller.

Follow the installation instructions, and you're set!

Think this would A. Fit a D4, and B. be of any use?

Ooooh, nice. I see it in there. I misunderstood what he meant by "If the stock O-ring is still stuck to the face of the motor, get rid of it."

Thanks!

It should, since the D4 and D5 are very similar (read: practically identical, aside from the motor... and maybe some small impeller differences).

Haven't had time to work up a curve for the D4 with Detroit top yet.

BTW, I got those pumps shipped out to you today (sorry for the delay)... I'll PM you a tracking number in a bit.

Just put my DtroitAC tops on today. Was easy as pie! Mmmm pie! But these things are fantastic and also a hidden bonus that I did not even think of was that I was able to get the two pumps even closer together since the rings were no longer in the way at the bottom of my build. So that was pretty sweet too! Thanks DetroitAC for these pump tops. Can't wait to play with them now when I go home. Just had enough time to get the tops on and leave for work. I think I am going to get some custom brackets made for this as well since it did not need as much clearance since it has no ring and could easily come down almost an inch.

I got my DetroitAC top in today as well. I don't yet have all of the air completely bled from my system, but my max Linpak temps are down 2C. The hotter (primary) core on the X2 is down 3C. My ambient is 1C higher than is typical too! I have to say, I wasn't really expecting to see more than 1C difference with this top. This loop must be more restrictive than I thought! I installed it on a MCP655-B along with DD FatBoy barbs. Just a note to anyone that might choose to use these barbs, you need to tighten them down until the flares are flush with the body of the pump head. I tightened mine to snug initially, and found that it wasn't sufficient. It may not hurt to get some thicker o-rings for the barbs if you get nervous about things like that. The install was a breeze, took no more than 30 minutes to remove the pump from the loop, swap the top, and get it back in for bleeding. It's been in and running for 2 hours now, no signs of leakage!

Thank you DetroitAC! Wonderful product!

My GPUs and CPU are now closer temperatures at idle. I'm seeing 24/23C on the GPUs and 24 on the CPU at idle. I was previously seeing 26/24 on the GPUs and 26C on the CPU at idle. All examples with an ambient of 22C.

--Matt

I got my top today, all I can say is WOW, the size is small as Sadasius mentioned above! I have not yet tested this top, but I am very happy with the quality and looks, not having to use the stupid ring to tighten the top to the pump is a great idea! DetroitAC has done an amazing job!! ;)

Yes there should be enough room. The diameter of the stock mounting ring is ~3.4" and my pump top is 2.8" wide, so there should be an extra 0.3" space.

I don't have a UN designs bracket, maybe someone else could check it to be sure.

I've got a silly number of them on hand :up:

I have two tops coming my way, hopefully they will arrive soon, in a few days.
and I happen to have the UN 360 bracket for the D5 (got two actually).
If you are not on the rush with this I can take measurements after mounting.
and see if the pump can rotate 360 degrees, which you specifically want to know if it can face up right ?

let me know.

2.8" is the width of the top
outlet is offset 0.9" from the center of the block

I'm also interested to see how this fits my bracket. I'm in the middle of doing the next revisions for my brackets and one of the criteria is that they are universal for all the different aftermarket tops.
I don't have Detroits top so I can't test it with the new revisions. I'll be watching this thread to see how things fit up.
By the way the top looks really well done Detroit.

Hey armeniandave,
If you are preparing a little revision for your UN brackets, I suggest offering just the small plate with screw and nuts will be a nice offer.
In that way, users can mount 2 pumps on the same bracket (as I am planning to do) and only buy 1 Bracket and the additional plate and not a complete new bracket.
Probably not a lot of user will do that but worth trying IMO.

Moreover, I think a new design which will offer vertical and horizontal 360 degrees rotation would be very nice.
You are already half way there :up:

On a side note, I really like your brackets, don't get me wrong, it's just an offer to make a great product even better :D

As I said, I will be posting fitment notes along with pictures for the guys here :cool:

One more question if you would please. How much more narrow is the pump with your top, than it was stock? It seems like it's quite a bit less wide with your top. If so, that would help the offset also.

Stock is 3.4" wide and mine is 2.8" wide, or are you asking something else and I'm not getting it?

Andy, I can confirm that the Detroit Thermo top on the (UN)designs bracket has the clearance for a inlet straight up orientation, plenty of clearance.
