Vigor iSURF II Hard Drive Cooling System - Keeping it Cool...

We receive a lot of interesting products in the labs for review over the course of a year. We do not always review all of these products, although we will at least make mention of them in our blogs or forums from this point forward. In the meantime, there are those products that sometimes deserve more than a mention for a variety of reasons. Today we have one of those products and it comes from Vigor Gaming.
Vigor Gaming is best known for custom gaming systems that provide a high degree of customer satisfaction along with a fairly reasonable price to performance ratio depending on the configuration layout. What most users might not know is that Vigor Gaming offers several component choices for separate purchase. Of these, the iSURF II Hard Drive Cooling System caught our attention when it arrived.
Not so much for the fact that it is a hard drive cooler, more so for the fact that it had a certain industrial art edge to it and it felt like a very solid piece of hardware. While the design was the most interesting aspect of the product, we wondered out loud if it really worked. As it turns out, it does work as we will see shortly.
In the meantime, let's take a quick look at the product design.

Actually this is bottom side of the iSURF II where the drive resides and is installed. The unit contains two 40mm fans rated at 20.7 dB(A), a blue LED, and separate power connectors for both, which is a nice touch as the LED tends to light up the room. In fact, between the face plate design and strength of the LED, our case resembled a Cylon in a dark room. The good news is that you can disable the power to the LED or move it vertically to block the output level.
Our noise measurements (room at 20dB(A)) revealed a measurement of 23.2 dB(A) in our test case enclosure. In other words, several other components in your system will probably generate more noise. Also, the fans can be reversed to blow hot air out the front of the unit instead of drawing cool air into it. In our test scenario we did not measure a difference in temperatures although your mileage might vary.

Unlike several of the hard drive coolers we have tested, the iSURF II does not utilize a solid plate to make contact with the drive. Instead, Vigor relies on a series of cooling fins and the solid side rails in order to dissipate the heat generated by the drive. While an unorthodox design, it does work provided the side rails are in complete contact with the drive.

Ah yes, the iSURF II with our test drive installed. Speaking of the side rails, it took a bit of effort to get the drive lined up properly so each of the rails made complete contact with the Raptor X. There is a fair amount of clearance on each side of the drive once installed. If you crank down the screws on one side without balancing the other side, there will be a 0.115" gap. This effectively increased our thermal results by 1C in testing. We ended up placing the drive in the cage, installed all six screws so the drive was centered between the rails, and then torqued the screws down in a criss-cross pattern until the drive was securely attached with both rails making full contact.

A view of the unit's topside reveals the curved design and additional cooling fins. The unit itself comes in any color as long as it's black, is designed completely of heavy gauge aluminum, measures 172 x 142 x 41.5 mm, and weight a hefty 586g. Current MSRP is $24.99 and we have seen street prices around $22.
Enough of the aesthetics, let's see how the iSURF II performs.
Test Setup-

We figured this particular setup would offer a generous amount of heat output in the case and it just happened to be the configuration we were testing in our Cooler Master Stacker 830 Evo case at the time. We performed our base test in the Evo's drive cage with and without the standard 120mm fan operating. We then removed the drive, installed it in our iSURF II hard drive cooling system, placed it in the bottom external 5.25" drive bay, and tested with the onboard fans in both an on/off state.
We performed our test scenario five times for each setup. We throw out the low and high scores and average the remaining three. We let the drives idle for 20 minutes for the idle results and then loop the PCMark Vantage HDD test suite three times for our load temperature results. We utilized both Active Smart 2.6 and HD Tune Pro 3.10 for our temperature readings. We also utilized a thermal sensor to ensure the results from the software applications were accurate. Our test room was kept at a constant 23 Degrees Celsius during the entire test routine.

The iSURF II out performs our 120mm drive cage fan slightly by offering a measured 1C drop in both the idle and load temperatures. While this may not seem like much, the actual temperature between the two installation points varied by 0.6C with the higher case temperature measured where the iSURF II was installed. Factoring in this difference, the unit offered a 1.6C improvement in temperatures.
What was most surprising is the result between the cage without the fan on and the iSURF II without its fans turned on. Our test unit offered a 1C advantage at idle and 3C during load operations indicating a robust thermal design by Vigor. We did not install rubber mounting grommets when we attached the iSURF II unit to the case, but acoustics did not differ from the isolated Evo drive cage in sound or tone.
We recommend the Vigor iSURF II Hard Drive Cooling system to those users needing to install an additional drive in an external bay based on the aesthetics and performance of this product. Of course, any Battlestar Galactica fans needing a Cylon theme will also benefit from the front bezel and blue LED design. In all seriousness, those users seeking improved hard drive thermals with case designs that do not offer hard drive cooling options will benefit the most from this product. For users in that particular situation, we would not hesitate to recommend spending $24.99 (or less) for the iSURF II. In fact, we already have for several test bed machines.
