The install was a bit more intensive than a Factory Intel or common aftermarket HSF Pentium 4HSF just because of the fact that the mounts (Nipples) are attached directly to the motherboard PCB via the 8mm bolts that attach under the PCB into the nipple that is directly above and around the CPU socketarea.The Nipples are made of brass or a brass like material in appearance.

Once the nipples are in place the install is rather similiar to the rest of the HSF on the market today for a P4. Dab on your thermal grease which is included or the brand of your choice, and bolt down the Flower HeatSink with the provided 17mm bolts into the nipples with a tapered spring in betweeen the 17mm bolt and the nipple. The tapered spring should be loaded with the heavier wound end up or with the tapering in the down position(under the 17mm bolt head).

Next is the Fan & Fan Bracket installation. Now Zalman provides a nifty bracket that appears to be universal fit to all cases. It attaches to the case via a VGA slot mount (Uses the existing screw down area of your case's PCI/AGP area to mount & hover over the Flower HeatSink) that allows for adjustment in a north/ south as well as in a east/west direction. Pretty good idea. The bracket is also slotted to accomodate an additional fan to be mounted over the PCI/AGP area on your motherboard for card cooling as well. Although this option may not be as aesthically pleasing to the eye for all you case modders and case window owners, it proves to be as functional as a blowhole fan on your case's side door. I do not recommend moving your case with the fan & fan bracket installed. Although the connections are good, the hovering position of the 92mm fan will cause movement when transported and may cause damage to other neighboring components. I suggest using a couple of thumbscrews on the attachment to the PCI/AGP area for easy on/off accessibility.

Installing the FAN MATE 1 adjustable fan speed controller was easy as silk and a very nice feature to include in this package. It is basically a variable speed fan controller with a 3 pin connection. My only problem with the Fan mate 1 was with bootup on my initial try of the unit. My bios gave an error beep when I initially started the system up due to the low RPM's of the fan. I had it set akll the way to the left which is the minimum RPM ~1600 RPM which Zalman calls "silent mode". This mode may prevent your motherboard from booting. Two solutions are to either crank up the RPM's (turn to the right) on the variable speed fan controller and avoid the bios halt or disable the CPU Fan Detected on your mainboard. Note Zalman strongly reccomends not running in silent mode if you are overclocking your processor/motherboard. Also be careful not to be aware of your RPM's when overclocking as it is quite simple to overlook when an adjustment is available.
