Final Words

When we first agreed to review PowerColor’s Radeon HD 5770 PCS+ Vortex, we weren’t quite sure what to expect. Whatever we were expecting though was that the card would be easy to evaluate in one manner or another. This didn’t turn out to be the case.

We’ll start with the Vortex’s adjustable fan, the card’s big feature. In short, the adjustable fan is a useless gimmick in our tests. Extending the fan doesn’t change the card’s temperatures and it only makes the card slightly louder. There’s no useful reason to extend the fan and hence there’s no reason to take advantage of the card’s adjustable fan. For all practical purposes, this card should be considered a double-slot 5770 with a fan that can be removed for an easy cleaning.

The 5770 is not a hot card in the first place, so the fact that an adjustable fan didn’t have a significant impact doesn’t really surprise us in the end. As we’ll see in some other triple-slot cards later this month and next month there’s definitely a point to a wider design, but it only manifests itself on larger, hotter cards that also go all the way with a triple-slot cooler rather than toying with the concept like PowerColor does here.

But while the adjustable fan is a gimmick, the overall cooler design for the Vortex is not. It’s generally as good as the reference 5770 which was already a solid design in the first place. Much more impressive is the fact that PowerColor managed to pull this off on a card over an inch shorter than the reference 5770 with no downsides to speak of. With a factory overclock it’s faster than, as cool as, and as overclockable as any reference 5770, all in a smaller package. Unlike the fan, this really is an impressive feat for the Vortex.

Finally we’re left with pricing. The 1GB 5770 market is fairly competitive, and as a semi-specialty card the 5770 Vortex is not competitively priced with the cheapest cards on the market. At $165 it’s not poorly priced but it’s also not a steal. If you need a shorter Radeon HD 5770, it’s one of only a few cards that will fit the bill, otherwise you have to look at the overclock and the included copy of Call of Duty – Modern Warfare 2.

Cards with a similar overclock – including PowerColor’s previous PCS+ 5770 based on the same PCB – can be had for as little as $140 after rebate. Since we haven’t tested the previous PCS+ so we can’t say too much about it, but ultimately the Vortex is only price competitive if you value a copy of Modern Warfare 2. Otherwise as one of the more expensive 5770s on the market, it should be possible to find a similarly performing card for less.

    This article totally reminds me of mythbusters. Will the fan work better while extended? As it turns out, myth busted!

    Great article as always guys.

    This card looks like the perfect mid range ati card.

    The only problem is I paid $175 for my HD4890 a long time ago (well over a year ago), and it is still faster than this card. Nothing exciting has happened in the mid-range for a long time.

    That thing got a HEMI? :-B

    The car that they based the diagram on looks to be the Camaro. Obviously Camaro does NOT use the Hemi.

    Looks more like a Mustang to me, but wouldn't have a HEMI either.

    You're an idiot. It is clearly a Camaro.

    There's no way having a fan closer or further will affect the airflow in a closed environnement (in occurrence the somewhat small duct).

    The only thing that can be affected, is the noise, when you use a bigger fan, you can reduce the speed of it, so the noise drop, and you keep the same airflow.

    Another myth people beleive in, is making the fan turn faster, will cool down the heatsink better. This is actually logical up to a point. The point where the heatsink itself can't transfert any faster the heat. Aluminium and copper have a limit to what amount of thermal it can transfert, eg: speeding up a 120mm fan more than 1200rpm, will not cool more your CPU. You'll need a better heatsink design that can dissipate more heat at the same time.

    Actually, separating the fan from the heatsink surface CAN improve performance by limiting the dead spot underneath the fan hub (fan shrouds on radiators, anyone?).

    Best thing a person can do to reduce heat and noise (aside from an aftermarket cooler) is to replace the cheapo stock goop on your GPU with MX-2 (or other quality paste). Simple, quick, do it right: great results.

    That's what AT should do! Take all of the mid-high range cards from both camps, replace the TIM, then test. *drool*

    Just put a stern warning on the article that it shouldn't be attempted if you're a real dummy who will end up bricking the card.
