- The Fan
The fan is a standard Delta black label fan that produces 38-CFM of airflow at a rated fan speed of 6800 RPM. It measures in at 60mm x 60mm x 25mm. As most people know who are familiar with these beasts, they are LOUD. The sound output is rated at about 46 dba. They also put out a high pitched whine that have left many folks complaining about it, but I have long since given up the concept of quiet when it comes to keeping everything as cool as possible. While the noise is very noticeable, it didn't bother me very much at all.
The GlobalWin folks have been using a simple mechanism for attaching the fan to the sink. it's two small wire clips that fit into the holes at the base of the fan. These clips then fit into cutouts in the heatsink where they are then affixed under a lip on the side of the sink. it's simple, but very effective. There is no noticeable movement of the fan while it is perched on top of the heatsink. No movement equals less noise and a more stable flow of cooling air.
- 3-pin connector into a 4-pin Adapter
I have stated before that there seems to be more stability in fans that hook into a standard 4-pin connection coming straight from the power supply. Cooler Guys seems to agree with me on that point, so have included a conversion plug to make the 3-pin connector into a 4-pin variety. While it doesn't allow you to monitor the fan speeds through the BIOS, I feel that the added reliability is a small price to pay. There is also a message on the Cooler Guys website concerning the use of the 3-pin connectors:
"We recommend powering this fan via the main power supply, not the mainboard"
The fan also comes with one of my favorite attachments a fan grill. I have had wires sucked into strong fans before within the case, and it's a horrible feeling to hear it happen. I also know of quite a few fellow tweakers who have found themselves suddenly missing some skin from their fingers when these hungry monsters of a fan went into a feeding frenzy. Let me assure you that a 6800-RPM fan can do a good deal of damage before you're even aware of it!
- The Heatsink
The heatsink of this unit is larger than that of the FOP-38. It measures in at a hefty 75mm x 68mm x 42mm. And yes, that is its size without the fan attached to it. It is BIG, but that's what helps it to overcome the battle of heat against your processor. The larger surface area helps it in spreading out the heat from the core, letting the strong Delta fan blow it away and cool off the entire system.
The clipping mechanism is a standard one used by GlobalWin. While it is not one of the easiest to apply, it is not too difficult and holds the unit in place very nicely. One thing that you don't want is for a heatsink to start moving around. That would defeat the purpose of adding a thermal compound and make the entire setup ineffective.
One nice thing about the unit was that it is the first GlobalWin product that I have ever received that didn't have that nasty thermal tape on the base. It was a refreshing change of pace, and saved me the time it takes to scrape it off and lap the base.
The base itself was quite smooth. This is also something unusual for the GlobalWin line. They normally have noticeable ridges going in at least one direction that need to be smoothed out before you install it. The base of the WBK-38 was very smooth and required no sanding on my part.
OK...enough of the technical stuff...can it beat out it's older brother?
