Conclusion: Expensive, Difficult, Potentially Worth It

My experiences with the Arctic Cooling Accelero Hybrid have revealed a product that's not unlike a powerful weapon. The end result of having the Hybrid installed on a GeForce GTX 680 is almost something that must be seen to be believed, and I imagine the AMD Radeon HD 7970 version is just as impressive (if not possibly even more vital given the GHz Edition's notorious noise level). At the same time, the Accelero Hybrid is really, really not for amateurs.

Creating something like the Accelero Hybrid is an uphill battle from the word "go." There isn't a whole lot that can really be done about that; they could produce a broad variety of individual packages for each card type, but that's not cost effective for them, and the Accelero Hybrid is expensive enough as it is. Assembling this kind of product was just going to be fiddly.

The problem is that I still feel like it could've been made at least a little simpler. The shroud itself feels chintzy, and the awkward shape and size isn't particularly attractive and oftentimes feels like it's even in the way a bit when doing assembly. Parts of this process could have been handled before the product shipped: all of the spacers could've been on adhesive sheets, the rubber pads could've been preinstalled in the shroud (and the shroud itself could've had spots that properly fit the spacers), and I have to wonder if they couldn't have even just built the shroud and waterblock as one single large piece. The instructions are for the most part detailed, but they aren't perfect, and more detail and care would've helped.

And then there's that price I keep mentioning. The Arctic Cooling Accelero Hybrid sells for a not inconsiderable $169 ($149 for the 7970 version), so they abuse your wallet, your time, and your fingers. With so much stacked against it, it's hard to fathom why you'd actually go through all the hassle. That is, until you actually see it in action.

What Arctic Cooling is asking for the Accelero Hybrid is an awful lot, but you actually do get quite a bit in the process. For the GTX 680 at least, the Accelero Hybrid is a substantial improvement. Thermals drop close to the 30C that Arctic Cooling advertises, which is tremendous, and the Hybrid is slightly audible at its worst. The card runs much quieter, much cooler, and because of this, the GTX 680 at least can actually gain a little bit of performance headroom. So you're looking at $169 and a couple of hours of work in exchange for a substantial amount of upside.

The price and difficulty of assembly rule out an Editor's Choice award, and this product is most definitely not for everyone regardless, but if you have the experience, time, patience, and funds required, there's a strong case to be made for making this upgrade.

    Get it while it's hot! Please update the article with new price at the end. This will definitely make it a stronger case for an award don't you think?

    I would consider buying it if it wasn't stuck on that GPU so I could maybe use it on my next GPU given that I personally couldn't justify the price.

    I just installed this cooler on my EVGA GTX 660ti Signature2 FTW and my temps are kind of confusing. Idle temps are around 24C which is the same as the stock cooler. The unusual part is that while running EVGA OC Scanner for 10 minutes, temps reach 45C versus 39C with the stock cooler. I know I have installed it properly as I've checked many times. If anyone is having the same problems please let me know so I know it's not just me.

    My Titan was only running at ~68% of TDP at 88F ambient (hot, I know) and this thing cooled the VRMs enough that I am now at 93.4% TDP at the same ambient.

    Installation was a needless trial, but put a movie on and take your time.

    I really like this unit - much more than the now popular Kraken G10, because you can fit Accelero Hybrid in a mini itx case!

    And of course, being able to 'pump' the how gpu air out of the mini itx case is important to avoid gpu throttling and maximize efficiency.
    Combine this with coolermaster Elite 130, nice!

    The best HSFs are spiffy coolers, but there are drawbacks to using the most efficient ones. The impressively-high-performing, dual-tower/dual-fan Noctua NH-D15 exemplifies them: first, it stands quite tall, at 16.5 cm, and can present a space problem in less than capacious cases. It is wide, and can preclude the use of RAM with any but the most modest heat spreaders, since memory stick height is limited to 32 mm. It is also massive, weighing in at 1.32 kilos -- almost 3 pounds! -- and has a high center of gravity, due to its stature. The effect of that much leverage on a vertically-mounted motherboard, if jostled, can easily be total destruction, with the processor, socket and rear mount being ripped right out! Even the static torque of the NH-D15, over time, could lead to mobo failure, which may not be covered by warranty.

    None of those issues exist where using a CLC, even one with integrated waterblock and pump: Silverstone's brazed, screwless waterblock eliminates a major point of leakage; Antec's Kühler further reduces obtrusiveness and physical stress on the motherboard by moving the pump(s) off-block to the fan axles.

    Rig damage by cooler sux, whether it's the result of fluid leakage from an AIO or excessive weight of a HSF pulling a board apart. Maybe a bungee counterbalancing a massive HSF would quietly help alleviate gravitational torqueing of the motherboard; if you install a CLC, inspect it often for signs of loss of seal integrity and leakage. "To be forewarned is to be forearmed."

    Each type of cooling systen has its strong points, yet comes up short in others. Given a bit more development time, CLCs will become more refined, and their problems largely ironed out.
