5 Lessons from my Ncase 3090 Build

An update on my Ncase M1 3090 deshroud build from December: [Original Post Here](https://www.reddit.com/r/sffpc/comments/klpwr0/3090_ncase_m1_deshroud/)

I have been tinkering with it pretty solidly since Christmas: Custom pslate cables, a larger EK rad, loop drain points, different fan configs... etc. etc.

Anyway, at some point in January the CPU started overheating. Not just "its a 3090 in a sff box - its going to run hot" overheating. I'm talking 90+ degrees across all CPU cores just after windows boot, (with GPU still in the mid 20's).

2 months later, I've learned a lot and it is completely sorted, Runs nice and cool now. I had to change the whole CPU cooling setup and I'm glad I did.

Now its working again: I have some things I would do differently next time - and save myself a 2 month headache. Here's the list:



1. **Get Custom Cables**. - I thought it was a 'nice to have' item, but its honestly essential in a small case. Forcing cables into gaps, stressing connectors, cable ties sticking into spinning fans, and the whole lot restricting airflow - basically money well spent.
2. **If water-cooling: use 16/10 soft tubing, not 13/10.** \- I started with 13/10 because I cannibalised an alphacool eisbaer lt aio. However I should have noticed it had bend restrictors across all of its tubing. I replaced much of it with standard Alphacool 13/10 tubing and then struggled with kinks trying to fit into the Ncase. I have now ended up with all EK stuff and 16/10 tubing, should have done that from the start.
3. **Don't pair a large radiator with a very small pump.** \- I am 99% sure my overheating problems stemmed from trying to drive an EK PE240 (40mm) rad with a pump that struggled to drive it: the Alphacool Eisbaer LT pump block. The Rad that Aplhacool AIO comes with is a 25mm ultraslim. There's probably some research I could have done but I didn't think about it - I would next time. - you should too.
4. **Go Custom Loop instead of AIO.** \- I originally didn't want to build a custom loop because I'd only ever used air and figured I didn't have the skills and there was a risk of undesirable wetness.. I should have just built a custom loop from the start. It isn't hard. Its actually a lot easier than the route I ended up going. I now have the iceman reservoir paired with an EKDDC pump. It was easy to set up and being able to fit the tubing to the case means there's much less superfluous tubing to force into a tight space.
5. **You can fit a cheeky 5th fan.** \- In the Ncase, a 90mm, under the PSU. It fits sideways behind the GPU and gives you 2-3 degrees better temps. I'm using a de-shrouded 3090 so cant comment on other GPU's. You can probably only do this with custom cables as otherwise your unsightly cable mess goes here.
