Can I please get some opinions on a build?
I bought a Ryzen 5950X from umart.com.au. I used to do my own PC builds back in the day, but haven't done it for 10 years so thought that I'd just pay umart to do it. Not so much for their ability to screw stuff together, but moreso so that they could comment on the compatability / suitabiliy of parts.
I wanted a small form factor so bought an ITX case and board (Asrock X570 Phantom Gaming ITX/TB3). Umart recommended a Noctua NH-L9i Low Profile Intel CPU Cooler so I went with that (I can't remember the exact reason, but they said to use the intel version even though it was an AMD build).
When the machine turned up though the thermals were through the roof. It sat over 90C mostly under moderate load. Under short bursts (software compilation) it pushed through 95 and the machine shut down.
So, I did what I didn't want to do, and started looking into the CPU and how to cool it. It didn't take me long to find [this](youtube.com/watch?v=SLTD6oJORTI) which pointed out that the 5950x is a beast to cool down. I started wondering if the little NH-L9i was really up to the task. I sent it back to umart. They responded with the NH-L9i was fine, but there was something wrong with that CPU and they would change it.
I wasn't so sure that the cooling solution would cut it, so asked if I could upgrade to something bigger. They refused to refund me for the smaller cooler, but I took the hit and bought a bigger Noctua NH-D15 anyway, along with an ATX case. The little ITX board looks ridiculous in the big box ... but hey, whatever.
Anyway - the machine finally got back here and appears to me to be DOA. When I power on the PSU I see red lights flashing under the MB and it fails to boot. I'm guessing that it was knocked in transit and something was damaged or unseated.
When I had a close look, I notice that the fan isn't sitting square. It appears that there's not enough clearance under it for the USB header plug, so they've just jammed it in to make it fit. I'm wondering if that's caused an uneven force on the CPU (or something) which has contributed to the boot issue.
Anyway - can I please get an opinion?
1/ I'm starting to feel that umart.com.au dropped the ball saying that the original spec was ok. Is the NH-L9i under specced for that CPU? Should they have known that and therefore refund me for it?
2/ If the above point is true, then should they have steered me to a bigger fan and an ATX case / board? I never would have bought an ITX board if I didn't think that the thermals would work.
3/ Is that NH-D15 installed poorly? Is it acceptible? I'm wondering if, when they saw that it didn't fit propertly with that USB header if they should have recommended to me another case or some other solution.
The whole thing has become a mess. It seems to me to be a cascading litany of errors which have compounded. I'm starting to feel that umart.com.au have let me down by not foreseeing these issues and are not taking responsibility for what is turning out to be a crappy result.
Am I being unreasonable? Should I just suck it all up and take my share of the blame? The whole reason that I paid them to build it was so that they'd take responsibility.
Thanks for any advice.
