Thermalright XP-90C - Page 3 of 4

More Room

Orienting the HSF in this manner frees up working room around the ram occupied dimm sockets on the DFI 915P-TAG motherboard. Nice option!

Nice Clearance

Good clearances all around. Well thought out design by Thermalright.

Inside Case

Installed in the case and ready for testing. Note the ample room around the HSF. Sufficient room between HSF and ram in this orientation. Also, ample room between HSF and video card.

Painless install with only a Phillips screwdriver for securing mounting brackets and stiffening backplate to the motherboard with 4 screws. Like the XP-90 there really are no negatives I can relate about the XP-90C other than the weight. Now if it will just cool down my Prescott!

TEST SYSTEM SETUP SPECIFICATIONS

  • Intel 3.4E 'Prescott', @ 3.7GHz
     
  • DFI 915P-TAG PCI-Express motherboard w/Dual Channel DDR memory
     
  • OCZ PC3500 High Performance, (2) 512MB DIMMs, running rated 217MHz FSB, Dual Channel @ 2-3-3-7 timings
     
  • Hitachi 80GB SATA HDD, 7200RPM (2)
     
  • Gigabyte GeForce 6600, overclocked timing frequencies: 600 MHz, gpu; 575 MHz, memory
     
  • NVIDIA ForceWare Graphics Driver, Version (WHQL) 71.84
     
  • Enermax 600W power supply
     
  • NEC 17-inch LCD712 monitor
     
  • 32-Bit Color / 60Hz Refresh Rate @ 1280X1024
     
  • Windows XP Pro with Service Pack 2
     
  • Microsoft DirectX 9.0c

TESTING

Tests included evaluations of three heatsinks. First, the stock Intel HSF, then an all aluminum XP-90, and finally the topic of this review, the all copper XP-90C. All tests were conducted using 'tweaked' system as identified in Test Setup using a closed mid-tower all-steel case. Airflow through the case is provided by two primary 120mm intake and exhaust fans. In addition, the case is fitted with an 80mm intake fan for cooling the two SATA HDDs and the contained 80mm and 92mm cooling fans for the 600W power supply.

My computer room can maintain 29C temperature consistently. I can reduce room temperature but have difficulty in maintaining a consistent ambient temperature, therefore, I opted for the 29C. This is probably higher that what most of you run in your computer area but I decided to go with this setting providing a good basis for these tests.

This is in no way a scientific test but simply an evaluation of each heatsinks capability of cooling under 'normal' circumstances that a home user can use as a basic comparison. All recorded temperatures were derived using temperature recording software and additional thermal probes used to check consistency in the results.

Idle temperature was obtained by running the test system with only minimal operating system and temperature recording software running for a two hour period before recording the temperature at 'idle.'

Maximum temperatures, for test comparisons, was running Folding@Home to maintain 100% CPU usage for a 24-hour period.

Fan selection was limited to the Panaflo 92mm High Speed fan as I was looking for both performance to cool the 3.4E Prescott while adding the desire for noise reduction. I found this 56.8 CFM, 35 dBA, fan more than adequately provided excellent performance while running exceptionally quiet for a fan moving this amount of air.
