The add-on fan is a great idea that takes the often used trick of mounting a fan over your card(s) to cool multiple GPUs and makes it a part that is incorporated seamlessly into the package. I found that at stock speeds the benefit of this fan was less than the advertised 10% improvement. However, there is a benefit in every scenario I tested bar one. The target audience for these SLI bridges are the high-end gaming crowd who want to get that last FPS or visual quality setting just because... well they can. If you have the means to populate all of the slots on your high-end gaming rig, the additional coin for an SLI bridge kit such as the MSI Gaming SLI Bridge kit, then the added cost won't be an issue for you. Pricing currently sits in the $50-$53 range for each one of these kits, with the 4-Way kit at $53 and the 3-Way kit coming in at $49.99. Meant for use with MSI Gaming GTX 9xxx cards, I found it the 3-Way bridge worked well with my reference 7 series hardware without any issues setting up the configuration. After going through my testing, this kit does a great job building performance through the addition of multiple cards and cooling the cards once in place. If a 3-Way or 4-Way graphics solution is beyond your reach, MSI does offer its Gaming SLI bridge connections for a 2-Way setup. Go get you some!
