Tagged: amd, radeon, fury x, pump whine
According to a couple of users from the Anandtech forums and others, there is another wave of AMD Fury X cards making their way out into the world. Opening up the top of the Fury X card to reveal the Cooler Master built water cooler pump, there are two different configurations in circulation. One has a teal and white Cooler Master sticker, the second one has a shiny CM logo embossed on it.
This is apparently a different pump implementation than we have seen thus far.
You might have read our recent story looking at the review sample as well as two retail purchased Fury X cards where we discovered that the initial pump whine and noise that AMD claimed would be gone, in fact remained to pester gamers. As it turns out, all three of our cards have the teal/white CM logo.
Our three Fury X cards have the same sticker on them.
Based on at least a couple of user reports, this different pump variation does not have the same level of pump whine that we have seen to date. If that's the case, it's great news - AMD has started pushing out Fury X cards to the retail market that don't whine and squeal!
If this sticker/label difference is in fact the indicator for a newer, quieter pump, it does leave us with a few questions. Do current Fury X owners with louder coolers get to exchange them through RMA? Is it possible that these new pump decals are not indicative of a total pump change over and this is just chance? I have asked AMD for details on this new information already, and in fact have been asking for AMD's input on the issue since the day of retail release. So far, no one has wanted to comment on it publicly or offer me any direction as to what is changing and when.
I hope for the gamers' sake that this new pump sticker somehow will be the tell-tale sign that you have a changed cooler implementation. Unfortunately for now, the only way to know if you are buying one of these is to install it in your system and listen or to wait for it to arrive and take the lid off the Fury X. (It's a Hex 1.5 screw by the way.)
Though our budget is more than slightly stretched, I'm keeping an eye out for more Fury X cards to show up for sale to get some more random samples in-house!
Retail cards still suffer from the issue
In our review of AMD's latest flagship graphics card, the Radeon R9 Fury X, I noticed and commented on the unique sound that the card was producing during our testing. A high pitched whine, emanating from the pump of the self-contained water cooler designed by Cooler Master, was obvious from the moment our test system was powered on and remained constant during use. I talked with a couple of other reviewers about the issue before the launch of the card and it seemed that I wasn't alone. Looking around other reviews of the Fury X, most make mention of this squeal specifically.
Noise from graphics cards come in many forms. There is the most obvious and common noise from on-board fans and the air it moves. Less frequently, but distinctly, the sound of inductor coil whine comes up. Fan noise spikes when the GPU gets hot, causing the fans to need to spin faster and move more air across the heatsink, which keeps everything running cool. Coil whine changes pitch based on the frame rate (and the frequency of power delivery on the card) and can be alleviated by using higher quality components on the board itself.
But the sound of our Fury X was unique: it was caused by the pump itself and it was constant. The noise it produced did not change as the load on the GPU varied. It was also 'pitchy' - a whine that seemed to pierce through other sounds in the office. A close analog might be the sound of an older, CRT TV or monitor that is left powered on without input.
In our review process, AMD told us the solution was fixed. In an email sent to the media just prior to the Fury X launch, an AMD rep stated:
In regards to the “pump whine”, AMD received feedback that during open bench testing some cards emit a mild “whining” noise. This is normal for most high speed liquid cooling pumps; Usually the end user cannot hear the noise as the pumps are installed in the chassis, and the radiator fan is louder than the pump. Since the AMD Radeon™ R9 Fury X radiator fan is near silent, this pump noise is more noticeable.
The issue is limited to a very small batch of initial production samples and we have worked with the manufacturer to improve the acoustic profile of the pump. This problem has been resolved and a fix added to production parts and is not an issue.
I would disagree that this is "normal" but even so, taking AMD at its word, I wrote that we heard the noise but also that AMD had claimed to have addressed it. Other reviewers noted the same comment from AMD, saying the result was fixed. But very quickly after launch some users were posting videos on YouTube and on forums with the same (or worse) sounds and noise. We had already started bringing in a pair of additional Fury X retail cards from Newegg in order to do some performance testing, so it seemed like a logical next step for us to test these retail cards in terms of pump noise as well.
First, let's get the bad news out of the way: both of the retail AMD Radeon R9 Fury X cards that arrived in our offices exhibit 'worse' noise, in the form of both whining and buzzing, compared to our review sample. In this write up, I'll attempt to showcase the noise profile of the three Fury X cards in our possession, as well as how they compare to the Radeon R9 295X2 (another water cooled card) and the GeForce GTX 980 Ti reference design - added for comparison.
