Re: YT Review: TR 3990X Cooling
That is indeed a rather large cooler!

Re: YT Review: TR 3990X Cooling
Hi both
What strikes me as being quite crazy, is that many moons ago, when CPU's such as the Pentium 4 (3.06 GHz version) used a 90-130nm process, the actual cross sectional area of the CPU was quite small, they were quite inefficient (the core needing say 1.5V), running at about 3 GHz and with TDP around 80-130W, the fan-based coolers were pretty small but usually ran at high-ish speeds.
Now, say 20 years later, we have CPU's based on sub-10nm processes, with larger cross-sectional areas, are far more efficient, (operating at lower core voltages) and still running at around the same 3 GHz mark, with TDPs of 25-165W and yet the coolers have grown massively.

Tim

Re: YT Review: TR 3990X Cooling
Its not often a air cooler outperforms AIO, hence why I thought id post these reviews.That is indeed a rather large cooler!
The Default TDP of the 3990x is 280W+with TDPs of 25-165W

Re: YT Review: TR 3990X Cooling
Hi Chris
Ah - you got me there, as I'm not an avid follower of AMD devices.
280W is indeed an awfully high figure. One wonders what is actually better: 1x 3990 at 280W or 8x Core i7 7700T each with 8 vCores running at 2.9 GHz and TDP of 35W each. I guess it depends what one is trying to do with the CPU !!

Tim

Re: YT Review: TR 3990X Cooling
Yeah I guess there are pros and cons for each.
Re: YT Review: TR 3990X Cooling
Small overclocks also very rapidly increase that 280w number
Re: YT Review: TR 3990X Cooling
This is actually not the right comparison: the 7700T is 4c/8t whereas the 3990x is 64c/128t (i.e. 128 vCores). You're therefore looking at 16x 7700Ts, amounting to 560w when operating at their BASE frequency of 2.9GHz. The 3990x is a hugely efficient processor and generally performs very far above 2.9GHz, even while staying within its 280w power limit.UBT - Timbo wrote: ↑Mon Apr 27, 2020 8:58 pm One wonders what is actually better: 1x 3990 at 280W or 8x Core i7 7700T each with 8 vCores running at 2.9 GHz and TDP of 35W each.
Re: YT Review: TR 3990X Cooling
I bought one of these Coolermaster Wraith Rippers for a system I built on an open bench chassis. It actually works a lot better than I had expected and pretty neatly tames the stock 280w. I haven't enabled the RGB outside of testing, but can say that it's pretty nice and would look good inside a windowed case.
It is a bit more expensive and also less effective than the Noctua NH-U14S, so definitely a bit more style over substance. Effective nonetheless, and I'm pretty happy with it so far.

Re: YT Review: TR 3990X Cooling
That video review said that the Wraith couldnt really handle the 3990X, or maybe that was when overclocked.
Re: YT Review: TR 3990X Cooling
Yeah, maybe it's because he was looking for high performance (i.e. overclocked) solutions. I do have some full custom water loops for that kind of thing but, given all of my issues, I've moved away from overclocking these chips for 24/7 running.chriscambridge wrote: ↑Thu Apr 30, 2020 3:54 pm That video review said that the Wraith couldnt really handle the 3990X, or maybe that was when overclocked.
This open-bench host is the 64 vCore 3970x and that chip shares the same 280w power draw as the larger 128 vCore 3990x. That results in a difference in processor frequency, but it's not a huge difference given rapidly diminishing returns as frequency increases. I am actually running it at just 200w usually, which is still ~50% more power per core than a 3990x at 280w.
In any case, at full 280w load, I see it hovering around 68-70 degrees in a warm(ish) room, open bench. The clocks look to be comparable to when I had that chip in a custom water loop too, so no noticeable impact really, not at stock at least.
Still, I believe that many of these other coolers are superior, particularly on a price-performance basis. I just liked the look of this one and thought that it would be fine at stock, which was my target. I am thinking of replacing the internal fan with my favourite fan - the Noctua NF-A12x25.
Re: YT Review: TR 3990X Cooling
Looking more closely at that video, the target power draw for his manual overclock is about 410w PPT (CPU package power target), so well above stock.

Re: YT Review: TR 3990X Cooling
I never manually O/C, the only thing I do is let the BIOS do any auto overclocking.
