Yeah this unit is fucked. Get refund
Just wanted to post another follow-up. I've installed a Noctua NH-U14S TR4-SP3 air-cooler and it works great. For 60% the cost I am getting 59C @ 3.9GHz full load. Also in the long run it will be nice not to worry about maintenance or possible failure. I would suggest for anyone else wanting to streamline their build with a sense of long term dependability to go with this low cost option.
The caveats are make sure your case is large enough, this particular model is very big and I managed to fit it in with less then 1 mm clearance on the side panel. Their is also the strong possibility it will block some of your ram slots. Not and issue in my immediate case as I am only using 4 slots, but if you need all 8 make sure you do the research.
Noctua AMD Threadripper Air Cooler Roundup
We take all three Noctua air coolers built for AMD Threadripper CPUs and put these to the test on both the 2950X and 2990WX. We run the NH-U14S, NH-U12S, and NH-U9 through the paces with both Precision Boost 2 and Precision Boost Overdrive using multiple fan configurations and compare these to the Silver Arrow and Wraith Ripper too.
Between the three air coolers the Noctua is the most readily available and most often gets discounted. The Silver Arrow performs the best in an absolute sense but that fan sounds like a tornado. If you strapped that fan to the U14S I think it will perform almost if not just as good.
Thanks for the review, wish I caught it earlier. I might have gone for the Thermalright Silver Arrow since it's going for only $10 more than the Noctua on Amazon right now.
Interesting thought. In the review the Thermalright achieves a 0.2 GHz gain over the Noctua in the 2950x overdrive test and a 0.3GHz gain over the Noctua (even with 2 fans) on the 2990WX overdrive test.
I think you can't ignore the number of heat pipes having a significant effect:
Noctua U14S: 12 pipes ($80)
Cooler Master Wraith Ripper: 14 pipes ($120)
Thermalright Silver Arrow: 16 pipes ($90)
Noctua a12x15 x3 on silver arrow might be the ultimate solution
You know what, I'm still within a couple weeks of the return period on the Noctua. Just ordered the silver arrow and going to give it a try.
Thinking about fans, I imagine the only real consideration in terms of performance is how much air gets moved (CFM). In terms of stacking fans I've actually seen tests where there is only a marginal performance increase when adding identical fans. When I think about it, if a fan is running say 1500rpm and moving 83 CFM, adding another fan running the same speed won't add any speed to the air, it will only add static pressure. When I think of 2 cars driving the same speed, they don't move any faster, but if they hit a wall there will be more force.
Essentially the performance increase in stacking fans is that the air will maintain speed when meeting resistance (cooler fins) but will not make the air go any faster than the rated CFM.
How about this for comparison:
3000rpm, 159 CFM, 41.3db
the specs on the Thermalright fan that ships with the Silver Arrow:
2500rpm, 130 CFM, 45db
I'm not a quiet pc nut, so I'm actually not too concerned about getting the quietest fan. Though it seems a lot of Noctua's claim to quiet fans is just to cripple the speed/CFM by adding their LNA wire which I think just reduces the voltage or something going to the fan. In that case I feel like you can just profile you fans manually by adjusting the fan curve. I'd rather get the most performance possible and if it's too loud with minimal performance gains, I'll dial the fan curve down.
The specs for the noctua fan that ships with their coolers is a bit different than the retail fans, iirc. I'd have to go check again.
Anyone know which side is the intake to the pump on the Enermax? I'm going to cut it and put in a reservoir.
If I remember correctly (95% sure), bottom one. Will check it later.
Ended up buying a Silver Arrow TR4, and idle temp wise it is about the same as the Enermax 360 lol. At load the Silver Arrow is actually better than the Enermax 360 I was using that is 7 months old. It was getting hotter faster at load than usual the past couple of weeks so I was thinking it was on it's way to failure.
The fan on the Silver Arrow isn't that great silence wise. It isn't loud, but it's a higher pitched whine sound when running full throttle and is very noticeable. It fits even with my GPU in the closest slot, but I moved my GPU to the next slot because it is very difficult to remove the video card (the little tab you have to press to release it from the slot needs a long thin screwdriver) and access to 2 fan headers is right next to the heat sink on my MB and can't be reached with the GPU in the closest slot.
Using small fft prime95 I still hit 85c @ 3.7ghz on my 1950x. I stopped it there, but for most of my other tests like 3d Rendering and Video compression the load was less and stayed in the 75c-78c range. That's with an ambient of around 21c. Overall a sideways move, but at least it should remain consistent.
I was right, top is outlet, bottom inlet. BTW hose I.D. is 1/4, O.D. 1/2.
I have but one upvote to give. Thanks!
For anyone looking for air cooling options I posted a detailed description over here:
The long & short, I got the best results with a Noctua NS-U14S cooler and replacing the fan with Thermalright's TY-143 140MM fan. So the extra heat pipes did nothing to improve the Silver Arrow, and even stacking 3 fans on it didn't do better than just having a faster fan on the Noctua.
