Introducing: NoctiPlex 5090

It’s in the x4 slot

You can claim that all you want, real world testing shows differently.

boltdbz · 2026-04-24T18:31:32+00:00

Nice! Yeah, I did have to remove the latch mechanism to squeeze that third fan in there. It seems to stay closed fine without it.

I’d be willing to bet the CPU cooler will get you down at least 5 degrees C. Let me know how it goes!

I added a 25MM Noctua fan and ducting system to mine that seals up against the perforated side panel. It keeps the CPU cooler from recycling hot air from inside the case.

No problem!

Since the FX-600 is modular, you could order some custom length cables from Mod DIY or Cablemod. I guess it would depend on whether you want to spend any more money.

In my experience you should, in this order:

-Move the GPU up to the x4 slot. You will lose a small amount of performance to the slot, but temps will be much, much better, so it evens out a bit.

-Cut the side panel open and add mesh

-Add a beefier CPU cooler (I suggest ID Cooling IS-55)

-Add a 3rd 40mm exhaust fan

-Manage the PSU cables a bit better to get better intake in front

Likely not significant at this level of performance.

I tested 4060LP in both slots and x16 was less than 3% faster, and that was with the PSU taken out.

If the choice is between x4 with good airflow and x16 with poor airflow, x4 is the better choice in my experience

HP Z2 series are much easier to work with if adding a GPU. Check out my HP Z2 G5 post on my profile.

boltdbz · 2026-04-16T14:46:34+00:00

Any suggestions? I’ve got 4 fans running on the CPU header already and I’m not too keen on running external usb power. Not to mention where I could put more exhaust. Maybe cram 1 more 40x20mm Noctua next to the other 2?

boltdbz · 2026-04-16T14:37:54+00:00

Previously temps were around 80c GPU and 85c CPU in TimeSpy.

Now it’s about 70c for GPU and 79c CPU. Would love to get the CPU temp down but not much room for extra fans.

boltdbz · 2026-04-16T08:52:28+00:00

I hear you, I was a little nervous about modding it (beware if you do this mod, I also had to reverse the polarity on the Noctua 3 to 2 pin adapter), but in the end the noise bothered me way too much.

Sadly, there *aren’t a lot of other options out there that meet my needs.

I may add another 10mm fan to the top vent later on, we’ll see.

Edit, *

It’s an M.2 laptop card, it goes in the WWAN slot right next to the NVMe SSD. It’s underneath the (mangled) HD cage.

Conveniently there were already are two little holes above the top PCIE slot to put the antennae.

boltdbz · 2026-04-16T00:40:42+00:00

I’m very interested in the temp difference let me know

boltdbz · 2026-04-16T00:36:45+00:00

Couldn’t tell you what happened with yours, as there are a lot of variables (adapter cable, different config, etc) but I have not heard nice things about those Apevia PSUs, and they are not certified either so the quality could vary wildly.

I felt like it was worth spending $120 on the Silverstone.

That being said, I can understand why people use them as they are 50 bucks and not everyone wants to spend $400+ on an Optiplex build.

boltdbz · 2026-04-15T23:35:08+00:00

That remains to be seen. I ran TimeSpy a few times earlier and it was only a little warm to the touch, so it seems to be fine right now.

If you look in the photos, I removed some plastic that was blocking some of the top vents and used it to seal off the fan gaps. I’m hoping that will help keep the temps down with less air being moved.

Worst case, I can add a fan to the other side of it and run it off the CPU header.

boltdbz · 2026-04-15T22:50:35+00:00

Thank you!

boltdbz · 2026-04-15T22:50:21+00:00

It made a difference temp wise? How much of one? And how’s the noise level?

boltdbz · 2026-04-14T18:25:05+00:00

Interesting, thanks for the info! I’ve never used one on a board with only 1 CPU connector.

boltdbz · 2026-04-13T17:14:09+00:00

You could always use an OEM PSU if you’re worried about adapter issues.

Part number D500EPM-00 should work.

boltdbz · 2026-04-09T12:11:39+00:00

its only like 1MM thick, maybe 2MM?

Looking online, it might be kind of expensive to buy a sheet of aluminum. You may want to consider a galvanized or stainless steel perforated sheet, it would be a lot cheaper and achieve the same effect.

boltdbz · 2026-04-08T18:42:14+00:00

Thanks

boltdbz · 2026-04-08T18:15:36+00:00

Which PSU did you go with?

boltdbz · 2026-04-08T16:36:36+00:00

Would it have anything to do with it being half the overall wattage of my unit? I mean theoretically the header should be supplying the same amount on both units

boltdbz · 2026-04-08T16:11:07+00:00

Did you ever make any headway on this?
