There is no fan control. Its full speed all the time with the rather loud 39dba idle. Most fans idle at 20-25dba.

How in the world does that make sense? And how is that even possible? Even if it doesn't offer PWM control (which is what I believe that they are saying), then it should still be possible to vary the RPM via voltage-control. And I'm pretty certain that they included an RPM wire. (If they didn't, then they're REALLY stupid, IMHO. But that could be par for the course for AMD in some things.)

Its a 3 wire, so the RPM one is included.

Even if they change it. That they currently think its a good idea alone shows how far from reality they are. Its a screamer.

The only other option that makes sense if it were 3 wire is that the AM4 platform is going to make it mandatory to have voltage control on the fan header.

The unit they demoed was a four wire fan though, so unless the actual boxed cooler is different than what's been shown, this shouldn't be a problem.
 
The quote is from The TechReport:

http://techreport.com/news/29577/amd-condenses-its-desktop-platforms-with-socket-am4

Interestingly, the Wraith uses a constant-speed fan that produces 39 dBA at all times. While that may sound like nothing special for a CPU cooler, AMD says that figure comes from testing in its own anechoic chamber. The company thinks that in the real world, the Wraith cooler will be one of the quieter components in a PC. The constant-speed fan could also be less noticeable than a cooler that has to ramp its fan speed up and down often.

AMD had some systems with Wraith coolers on display, and going by the tried-and-true "put your ear right up next to it" method, the Wraith seems to live up to the company's claims. While overclockers will still want to set the Wraith aside for a more capable solution, this boxed heatsink is a nice improvement over the older boxed cooler for FX CPUs, which could reach 53 dBA under load in AMD's testing.

TechReport is obviously compromised though now that Wasson is at AMD. 😵

Most high-end gamers should know that 39dB is effectively silent in a high-end rig.

It's not that loud to me, especially once inside the case.

Even if it's not fixed, it's a stock cooler! The people that are too sensitive to fan sounds wouldn't use it anyways.
 
The problem with AMD's heatpipes coolers were always those crappy 70x10mm fans they came with. If they could redesign the AM2/Cooler Master one (according to SPCR it was better than the AVC one that came with AM3+) to fit a 80x25 fan, you would have a solution to the noise problem.

I never could understand why would they keep releasing stock coolers with 70x10mm fans, only the fan that came up with some fX 4300's was bearable and moved good air(it is actually 70x15 but has 5mm standoffs, so the propeller really is 70x10).
 
Constant RPM makes sense from a warranty perspective I guess, it should result in less fan failures during the period they cover the product. Won't help with standalone sales, though.

Its the same as Intels stock coolers. They work for what they should, but no more than that. All about cost and dimensions. I wouldn't be surprised if Bristol Ridge shipped with smaller coolers due to 65W top SKU (it seems). But its a bit harder to predict with AMD due to the low volume.

Its a four cable 4-pin PWM Fan

It's a 4 pin fan, I doubt it is designed to run all the times at 100% as quoted a few posts above, motherboards should be able to control that fan.

Still, it's all an improvement over the usual AMD stock cooler and it's welcome. The noise profile of that HSF is much less annoying.


If AMD keeps factory overvolting their CPUs/APUs by a ridiculous +0.1v or more, their cooling solutions will be noisy no matter what. Maybe we'll still have to keep correcting that by hand on the new platforms and products.

It´s a huge improvement over the old one (regardless of the model), however you´ll know the situation is pretty grave when we are expected to get excited about a stock cooler. A cooler which still be dispatched immediately by any sane person (especially at 39dB) :'(

I'm pretty excited about it! If I ever recommend an AMD CPU to somebody, it'd be nice to know that they don't have to buy a separate CPU cooler. This is a good thing, IMO.

Sure, I agree...
Just pointing out that it would be nice to have something actually new for a change. The newest desktop CPU design is 38 months old and the newest desktop APU design is 24 months old 😵
