5800x3d Air Cooler

Ive just got the RGB Peerless Assassing today for my birthday. Very pleased with it. Before using a AIO my 5800X3D was hitting 79c full load using Cinebench multi test. After installing PA its now hitting 69c tops. Idling @ 26c too.... Win.

Yeah was looking at that and the Peerless Spirit but concerned about RAM clearance as I'll be using all 4 slots....

Try just using the middle fan. I built 5800X3D rig for someone else and used the spirit with only the middle fan for asthetic reasons. (Because the other fan only clears the RAM when it's mounted high and sticks up over the heat sink.)

Compared to the D15S setup on my primary rig, the single fan Spirit games the same, and all-core stress testing (R23) reaches my 87C temp limit sooner. (Neither cooler can stop the X3D part from hitting the temp limit indefinitely)

It used to bother me that the X3D parts were capable of hitting the temp limit even with strong cooling, but once AMD allowed setting a custom temp limit in later AGESA versions, I just set it to 87C and let the chip downclock in the off chance that I do something that demanding. (Just gaming has never got the chip that hot.)

I realize "just let it downclock" is probably blasphemy on an OC forum, but the 5800X3D's gaming performance comes from its massive cache rather than clock frequency. Also, gaming is it's primary job and temps are fine there anyway. When I occasionally use it for rendering video, I might get the video rendered a *little* quicker if I had a 360mm AIO, but not enough for me to care.

*edit* just retested and the single-fan spirit stayed just under 85C for a full benchmark run. I think I either looped for a longer period of timeand / or had a higher room temp last time. (23C this time)

I also decided to retest my D15S rig, and it actually runs *hotter* than the single-fan Spirit setup. (86.4C)

Only thing I can think of is the two rigs have different SOC voltages. The Spirit rig is running 3200MT RAM and an SOC of 1v. My primary rig is running 3600MT with an SOC of 1.1v.
That and just general silicon quality. They both score within 100 points of each other.

PS120 is massive lol, you can't see my tiny ITX Mobo, had to move the front fan up, as my ram is a tad too tall... Big improvement over the 140MM AIO that comes with the NZXT H1 V2 in terms of performance and noise.

5800X3D with a dark rock pro 4

I did want one of these, was bullied into a PA120SE and turns out it's proven better - which I didn't know till after I bought it...

Thermalright Peerless Assassin 120 is the performance king for £30.

This, was shocked it was better than the Dark Rock Pro 4 I wanted (that beats a Noctua NH-D15), despite not being as tall as the DRP4, so I'm very happy with mine, looks alright too with the black fan's too ;)
It also appears to be pretty much silent with a few lil tweaks, I run my BeQuiet case fans at something laughable like a fixed 540rpm, and my entire rig is silent, other than the gpu being massively undervolted, the rest is stock, never seen the cpu go above 65c, so I'd imagine a 5800x3d wouldn't go much above 85 at worst with my meshy mid case and big fans? One day I'll find out, but personally don't feel the need for anymore than the 5700x atm.

My friend uses Hyper 212 Black on 5800X3D and i have Dark Rock Pro 4. We both have identical temperatures, my conclusion is that there's not much difference which aircooler you use - it still peaks quite high, but overall average temp is not an issue with any reasonable aircooler. Also undervolting helps a lot(-25 all cores is stable for both of us and -30 not stable).

just replaced a hyper 212 with a phantom spirit 120. Load teams dropped 11 degrees. Idel temp is 22. £30..... you cant go wrong (unless you have tall ram... then you can)
