PRODUCT INSTALLATION AND TESTING
Tightening the screws in a criss-cross pattern, I was able to bottom the screws in the mounting holes, but this may not be true with all coolers. At any rate, the mounting plate displayed a bit of a bow when viewed from the side, indicating good contact with the backside PCB.
As you can see, the HR-11 fits nicely into this system and the finned area will reap the benefits of its proximity to the nearby exhaust fan. During installation, I encountered no interference issues either on the card or in the case. Let's see how the HR-11 performs.
For this review, I've chosen a DFI Infinity P965-S motherboard coupled with an Intel Core 2 Duo E4300 Allendale processor (overclocked to 2.4 GHz, +0.1 Vcore.) The other components are listed below.
- eVGA 8800GTS graphics card with OEM cooler and Thermalright HR-11
- Buffalo Firestix PC2-6400 (1024mb X 2) memory
- Zalman ZM600-HP heatpipe modular 600 Watt PSU
- Western Digital Raptor 740 SATA hard drive
- Samsung DVD-RW SATA drive
- Zalman Z-Machine GT1000 chassis (92mm intake fans @ 5V, 120mm fan @ 12V)
- Zalman Reserator XT liquid cooling system
The following parameters were used throughout testing:
- Arctic Silver 5 TIM used on the CPU waterblock.
- Ambient temperature kept at a constant 21C.
- Idle temperatures were recorded after two hours of zero load after booting to the desktop.
- CPU and GPU load temperatures were recorded after two hours of maximum heat testing using Stress Prime 2004 Orthos, and 3Dmark 2005.
- CPU Core temperatures were logged with Core Temp (v. 0.95.)
- GPU temperatures were logged with Nvidia nTune.
CPU Idle and load temperatures were recorded at a 33% overclock (2.4 Ghz.) with Vcore raised by 0.1V.
The above results are included as reference numbers for this system without the Thermalright HR-11 installed. As you can see, the GPU temps are consistent across CPU cooling platforms, even when case temps dropped a bit with the watercooling system. Using the same testing parameters with the HR-11 installed, I got the following results:
Ok, so these results aren't earth shattering. They do, show that the HR-11 is performing as advertised. There's a significant drop in load temperature and overall case temperature is lower, as well. Like I said, this is not a huge performance jump, but at the right pricepoint, the HR-11 may be a nice addition to an enthusiast's cooling arsenal.
