Small build, high temps, need advice

[razor007]

So initially I finished the loop today. Very tight fit. 6700k and 1080ti.
Intake fans on 240 rad are a bit obstructed, yet they pull decent amount of air from the side vents.
Had issues with CPU temps but when I run aida GPU stability test it peaked at 80 and idle temps were at 20s gpu was hovering around 45 so pretty happy but I had an opened panel.

Now moved it to the desk and aida fpu test throttled after a minute.
Idle at mid 30s, playing witcher 3 and my cpu was between 60-70 and gpu warming up to 56 just after 20 minutes of play.
With those temps the fluid is going to be too hot for my liking, and when I took the panel off you could feel the heat I side.
Without the panel temps got only slightly better.

What can be wrong?
Not overclocked, stock voltage 1.28 on cpu
Is it the airflow?
I am devastated.

Any help is appreciated

Got 240 on intake and 120. This was the only way to mount fans, rads so I can squeeze the fittings in.
Only way I'm afraid i looked and tested other options. According to Jayztwocents pull or push makes hardly any difference so went ahead

Playing either getting 56 on gpu and 70 on cpu after 20 minutes I think is not good

Not ideal maybe
I have never done a small case build
So nothing to personally
Compare it to
But if it does not go any
Higher than that it's still quite well within
Tolerable range
Reseating the block would be
An obvious thing to try though

Would need to drain and dismount everything. I'll pass for now and look at other case options similar size, nevertheless, i like the way it looks though, definint e10/10 for estetics,
cooling performance not so great though

Yes, I had it running for 12h, and been moving the case about, blocks are buble free, can only hope the same for rads.
There is not enough flex in the bottom tube going to 120mm rad to lift the block in order to re-seat.
Worried it would leak if tampered with

With such short tubing I would struggle to fit in quick disconnects
I looked at this option as I liked the idea

What is the case?

Metalicgear Neo mini itx. Phanteks makes them.
I will open up the bleed valve on the res tomorrow and move it about see if any air come out but the level of liquid was stable.

There is your problem. Incredibly throttled airflow through that front panel with only tiny vents on either side to allow air in. Is the mesh on the vents removable? I removed them from my H440 and the temps dropped by a couple degrees.

To check for air, whack your pump up to full and give the case a wee wobble. If you can hear sloshing or trickling then there is probably some air in the rads but it's probably not much, and probably isn't causing the high temps.

If I were you I'd be looking at ways to increase airflow and reduce heat output. Improve airflow by setting a more aggressive fan curve and reduce flow impedence, lower heat with undervolting and frame rate caps in games.

Thanks, I'll check if I can remove the dust filters after work.
What is the lowest voltage I can run the cpu with? Never messed with cpu voltages

Thanks Lucky
You're right more testing required. It us flex tubing so hope more resistant.
I took the front panel off and maxed at 68 playing witcher for 30 minutes, put the panel on and it went to 76 in a few mi utes, also temp on gpu had risen by further 6 degrees with panel on.
Improving air circulation may help

Thank you all for your thought it is really helping with troubleshooting.
Radiators are both xspc. Rear is slim and front is around 3cm thick crossflow,

Crossflow made more sense with the design at the time as standard rad would need some extra fittings to divert the flow back to the pump. Did some reading and there was literally no difference between the two hence the choice.


There are no other fittings for the fans I'm afraid, had to mount the pump in there and cabling round the back.

Fans pulling on the front rad were only option, otherwise I could not squeeze the fittings
at the bottom, since pump has to go first and rad to follow, rad need the fitting attached otherwise I would not be able to tighten the fittings.
Lol the way I squeezed it all feels like the only way you can get those parts in this case with this pump
I can go o or in detail if needed.

Fans are all noctua staric pressure optimised.

Any tips on how to drill a front grill in the aluminium case? that us always 8 degrees less if I do that
