The installation of the Ultra Products P4 LGA775 CPU Cooler is quite easy. After removing the motherboard, attach the mounting plate to the underside of the PCB so that the holes on the mounting plate line up with the socket holes on the motherboard. With the adhesive backing keeping the mounting plate in place, re-install the motherboard into the chassis. After removing the protective film from the copper based and evenly applying the thermal paste, set the heatsink in place atop the Intel Pentium 4 processor. With the screws aligned into the mounting plate, evenly tighten all four mounting screws. After that, connect the 4-pin fan connector to the CPU fan header on the motherboard. We installed the heatsink in the following system:
|Processor:||Intel Pentium 4 530 (3.0GHz)|
|Motherboard:||DFI LANPARTY UT 915P-T12|
|Memory:||2 x 512MB Corsair XMS PC4400|
|Graphics Card:||Gigabyte 6600GT (GV-NX66T128)|
|Hard Drives:||Hitachi 80GB SATA|
|Optical Drives:||Lite-On DVD-ROM|
|Cooling:||2 x 120mm case fans|
|Power Supply:||Thermaltake Purepower 460W|
As usual for our CPU HSF testing, we allowed the system to idle for 30 minutes followed by then stressing the CPU for another 30 minutes. LM_Sensors in conjunction with GKrellM 2.2.4 monitored the CPU temperature. During testing the ambient room temperature was at 21°C. For comparison purposes, we compared its performance against the Prime Cooler Hypercool 4+.
As you can see from our comparison of the Ultra Products Socket 775 CPU Cooler and the Prime Cooler Hypercool 4+, that this low-profile heatsink does come at a cost of performance. When idling, there was a 2°C difference between the heatsinks and when straining the processor with 100% load. there was a 3°C difference. Keep in mind, the Hypercool 4+ is a fairly large copper heatsink, similar to many of Zalman's CPU heatsinks. As for the noise level, it was noticeably noisier than that of the Prime Cooler. Although this may be a nice heatsink for users running stock speeds that are looking for a low profile design that doesn't cost an arm and a leg, for the overclockers this heatsink simply isn't the best choice. Hopefully through future revisions Ultra Products will be able to offer a viable heatsink for the overclocking crowd.
