Hi All

I have a MO-RA IV 400 on order, and was looking for some feedback on my plan to integrate this into my current setup.
I currently have an EK CPU & GPU Block (with active back plate), an FLT 240 w/D5 pump and a single thick (X series) 420 rad.

Whilst the above generally works fine and stays relatively cool, longer gaming session can push the temps up, so I have ordered the MO-RA IV.
My doubts are generally around loop order and pump requirements. I also have a second EK FLT w/D5 pump and was planning to attach both to the MO-RA inlet/outlet respectively, will this be enough to keep a decent flow rate through this kit?
Additionally, should I keep the X420 rad in the loop as its already fixed to my Thermaltake Core P5 case? It could fit pretty much anywhere into the loop, even between the CPU & GPU block. Would this serve a purpose, or would it just be pointless overkill?

All thoughts welcome

cheers

The coolant temp is generally around 32-35c after an hour or so, but on occasion, particularly after gaming for quite a few hours it can hit 45c+ I tend to stop playing at that point and let it cool down a bit.
It doesn't help that my OH loves to have the heating on full whack in the winter, so my temps are generally higher in the winter than the summer.
I really just want to get the temps as low as possible.

Is that the new mora that can take 9 x 200mm fans
Or 16 x 140mm fans?
Wouldn't think you also need the 420mm
But it won't hurt to use it since it's there anyway

I am definitely in favour of using 2 pumps
Even if one d5 would suffice
Having 2 means a pump failure doesn't mean the pc
Is out of action

45c is kind of warm for coolant
But unless you're using petg it's probably still OK

Sounds like ambient room temperature
Will be your biggest issue

Hey, thanks for your input. Really good point about the dual pumps adding a form of redundancy.

It's the MO-RA IV 400 (4 x 200mm fans), it should go nicely with my Thermaltake Core case/frame as they are roughly the same size.

I agree that 45c is a bit warm (I'm using the EK ZMT 16/10 soft tubing), hence my plan.
Whilst the ambient temp certainly isnt helping, the loop inevitably heats up to 40C plus over time even when its cool (windows open etc). I might end up just putting the MO-RA on the window sill and cracking the window a bit :D
 
If the tube wall is thinner I would expect it to be less robust but not flimsy. Thats pretty surprising, is it easy to kink?

The CPU is undervolted, and all cores are restricted to 5.8, Its been like that since purchase. It doesnt require a lot of voltage so I think I got lucky however, the situation with 13/14th gen is always in the back of my mind.
I haven't undervolted the GPU, power is all default but there is a mem oc, and a slight core oc on that. I think I will see how it behaves with less voltage now though.

I bought some barrow quick disconnects on sale earlier in the week for this project, just opened them and they seem really restrictive :(
 
Hey Pre

The thermaltake core series are not a case in the classic sense. Its more of a frame or an upright test bench, so there is no internal case heat to exhaust, its all open.
Bit messy at the moment (mid project), but for context:-

I was planning to use 2 of the EK FLT tanks w/D5 pumps (I also have an FLT 120) connected to the inlet/outlet of the MO-RA as I understand there is a considerable amount of distance to travel inside the rad.
Is there a better way to do this?
 
Cheers Pre, both you and Mcnumpty have put my mind at rest.

Do you know of any quick disconnects that don't restrict flow?
I ordered some Barrow TZKMF-V2 and they are very restrictive. So much so that it takes effort to even blow through them.

Sincere apologies if this sounds like an absolutely Noddy thing to ask, but you did connect the male and female quick connect fittings together for your blow test?

Ha Yes, they were coupled at the time of the test, I do understand why you would ask though, I've seen people do sillier things.
I've been doing a bit of research this morning and most of the comments regarding these specific QD's is that they are very restrictive. Koolance QD4 seem to have the best reviews, so I might get those ordered today, unless some kind soul can suggest something better.

I am definitely leaning towards the window sill option, and have ordered plenty of tubing in case I do go down this route. Thanks for the tip regarding the order of powering up the pumps during filling, I was already wondering what the best way to do this was.

The pump order I was planning on using was simply to make it easy on myself, I was going to move the FLT 240 up, and pop the 120 in below it. The positioning of everything then just naturally leans towards that order.
I am surprised to hear that 2 pumps directly in series would work just as well though, rather than spacing them out about 50% of the way around the loop.

I love your idea of putting the rad in another room, if only I had a spare room. The fan and pump noise doesn't bother me though to be honest, I always have headphones on.

Why is your rig out of commission, are you working on upgrades too?


cheers

Hey thanks for the thorough explanation. My take from this is that it really doesn't matter when I place the pumps, and can just go with the most convenient option which is really good to know.

Sounds like yours is going to be a great build, what GPU are you planning on going with? Nvidia 5000 series might be available by the time you get your arse into gear :cry:

if the FLT didn't come with the original D5 top then you are limited...

This exactly, it's purely because I already have the parts, and thought it would 'match' everything else.

You may be lazy mate, but at least your honest about it!
I had a 3080ti for a while, great card for 1440P.
 
Yeah, I thought I had scored a bargain, but the old adage "you get what you pay for" comes to mind.

I don't mind paying a premium for something that works and is well built, I just cant work out how to get the QD4 down to G1/4 female :confused:
 
Thanks Numpty, I hadn't even considered trying to push the EK tubing straight onto the compression variant of the QD4. I think you're correct though, and I should easily be able to get them on with a bit of patience. This will save so much hassle.

RE the URL, if a moderator could advise if links to manufacturer sites are allowed I would appreciate it.
OCUK don't have the QD4's unfortunately.
 
Thanks again Numpty, this is really good to know, I'm sure I will be able to make them fit.

Were yours the QD3? (I am struggling to source the QD4 without paying really high shipping direct from manufacturer). The QD3 are in stock on OCUK.
 
Thanks again Numpty

In the end I decided to just order it all directly from the manufacturer. OCUK didn't have both the male and female QD3 in the correct compression size fittings, and I was struggling to find them anyway.
I went for the QD4 threaded type, with gauge adapters, and then the G1/4 swivel fittings. The latter is on back order, so I will have a bit of a wait before they arrive.

MO-RA is out for delivery today, so I am going to be sat looking at it for a while until I can get the QD's and associated fittings :(
