OCZ Glacier 2 -The FeaturesThis particular unit falls into the "Budget" category, but don't let that fool you. It is a standard sized 60mm x 60mm heatsink that has a 36cfm fan mounted on top. It also has a 40mm circular copper insert in the middle of the heatsink base to help dissipate heat at a very respectable rate.Overall performance was very good for a lower priced HSF. It was giving me better results than the GlobalWin FOP 32-1 that I have been using. I believe that this was primarily due to the copper insert. Copper is a good conductor of heat, so the added presence of this metal in the base helps to spread out the heat so that the high-speed fan can get it away from the processor. This means better overall cooling and lower temperatures for both the core and the system.- The FanThe fan in this HSF combo is a 36 CFM model made by the Dynaeon Company of Taiwan. OCZ claims that it is "much quieter than a Delta fan". While it is quieter, I'm not sure that I agree with the much part of their statement. Even so, the noise was not distracting and had no impact on my normal computing. Power for the fan is by means of a 4-pin connector. This means that the fan will need to be hooked straight to one of the harness connectors that come from the power supply. I personally prefer this setup since the power from the PSU is more stable than the small 3-pin molex connections on the motherboard. Granted, you can't monitor the fan speeds through the BIOS, but the performance has always seemed to be stable.One nice feature of the fan was the fan grill. While this may seem trivial, it's a part that is often neglected by companies that sell so-called "quality" components. Now I'm not the type to stick a finger in the thing just to see if it hurts, but I can tell you from experience that it's a gut-wrenching feeling when you're in the middle of a furious deathmatch and you hear one of the wires inside the case get sucked up into the fan blades. Talk about a blown match!- The HeatsinkThe heatsink of this unit is pretty standard. It measures 60mm x 60mm x 35mm. It is an aluminum block with 15 fins going all the way across the sink. The retaining clip is standard for the most part, but has a small plastic covering on the side where you push down to attach it to the mainboard. This is very nice on the fingertips and makes the installation process much easier.
OCZ Glacier 2 -TestingI ran a small series of tests on the unit to see how well it performed on both a standard speed system and an overclocked one. The base system consisted of:Antec SX1030 Tower CaseAbit KT7 (non-RAID)AMD Thunderbird 1000MHzArctic Silver Thermal Compound256MB PC133 CAS2 SDRAMCreative Annihilator2 GTS w/ 32MBSound Blaster LiveWestern Digital 20.5GB @ 7200 rpmI ran the tests with the processor clocked to 1000MHz and then again at 1100MHz. The overclocking was done by FSB settings to try to create a hotter processor. This gave results that showed how well it performs under both normal and excessive conditions. The testing itself consisted of monitoring the processor temperatures when the system was idle, after a heavy deathmatch of Quake3, and then after a looping of the demo included in 3dMark2001.- 1000MHz
