PRODUCT INSTALLATION AND TESTING
With the help of the instruction guide, installation is relatively easy. The guide is very helpful with lots of photo illustrations covering all the various applications. The only comment I have is that I would recommend that the protective sheet be left on the foam insulator, as it is very difficult to remove, should you wish to change coolers in the future. Prepare the backplate, Mylar sheet and foam insulator in the order specified and add the screws.
After the assembly is in place, a fiber washer and standoff is placed on each screw and snugged up to the board.
After applying the thermal compound, the Big Typhoon can be placed on the chip and the top H-bracket is then secured onto the screws with the nuts provided. These nuts can be very difficult to tighten, as they are under the fins and access is limited. I used some knurled nuts instead, making the installation much easier. Plugging the 3-pin connector into an appropriate motherboard header completes installation.
As you can see, the Big Typhoon is very big indeed. I noted no interference with any motherboard components, but this cooler is tall and wide which may be problematic with some cases and components. On the plus side, downward airflow will cool the memory as well as other components around the socket.
I test all coolers in the bare frame pictured above. This eliminates any effects that a case might introduce. Keep in mind that temps inside your case will be higher; how much higher depends on the case and airflow. Let's move on to the testing phase and see how Thermaltake's Big Typhoon performs.
The testbed we'll be using consists of the following:
-Intel P4 D 805 processor
-Asus P5LD2 motherboard
-OCZ DDR2 PC5400 (512mb X 2) memory
-Thermaltake Purepower 600W PSU
-Western Digital WD800 SATA hard drive
-Lite-On CDRW/DVD Combo drive
(When looking at the results, please keep in mind that this processor runs very, very hot.)
The following parameters were used throughout testing:
Arctic Silver 5 TIM used on all coolers.
Ambient temperature kept at a constant 21C.
Cooler allowed to burn-in at maximum heat setting with Prime95 for two hours to partially set the thermal paste. The computer was then shut down for one hour.
Idle temperatures were recorded after one hour of zero load after booting to the desktop.
Load temperatures were recorded after two hours of maximum heat torture testing using Prime95, each core loaded with its own iteration of P95.
Fan speed was set to maximum for all testing.
Idle and load temperatures were recorded at stock CPU speed (2.66 Ghz.) and at a modest 10% overclock (3.0 Ghz.). Vcore was raised by 0.1V during the overclocking runs.
The results show that Big Typhoon does an admirable job if taming the tremendous heat generated by this Pentium D 805 processor. Though not silent, it is very quiet and would probably be unnoticeable inside a case.
