Testing & Results

Testing Methodology

The following programs were used during testing;

  • FurMark build 1.6.0 - For monitoring temperatures under load.
  • ATI Tool v0.26 - For attaining max stable O/C data.
  • RivaTuner V2.24- For driver level overclocking.
  • CoD-4 Modern Warfare - For real world stability testing.

Ambient case temperatures were measured using a relatively cheap digital case temperature monitor and were consistently 23°C / 24°C. 30 minutes were allowed for the temperatures to stabilize before starting each test, idle temperatures were then recorded. After that FurMark was allowed to run for 10 minutes to load the GPU and find maximum temperatures. Each test was conducted 3 times and an average was taken from the 3.

The tests were conducted under the following conditions.

  • 9800GT with stock cooler attached
  • 9800GT with ProlimaTech MK-13 attached - No fans - passive / silent operation
  • Max O/C on 9800GT with ProlimaTech MK-13 attached - ATI Tool / Riva Tuner (Core 720MHz / Memory 1140MHz / Shader 1800MHz)
  • Max stable O/C without instability during gaming on 9800GT with ProlimaTech MK-13 attached - CoD4 (Core 675MHz / Memory 1080MHz / Shader 1687MHz)

The MK-13 VGA cooler will be tested with two Xigmatek XLF-F1253 120mm LED cooling fans. Many other fans are available that may give better performance and/or airflow, but where silence is concerned these fans sit up there with the best of them, they are the only identical set of two 120mm fans I have to hand. Fan speed will consistently be at 100% during testing as I know my fans run nice and quiet at full speed.

Test System Hardware

  • Video: PNY GeForce 9800 GT 512MB (G92 65nm)
  • Motherboard: ASUS P5B-Deluxe Wi-Fi/AP
  • System Memory: 2GB PC2-6400 OCZ Platinum Rev-2
  • Processor: Intel Core 2 Duo E6600 2.4GHz @ 3.60GHz
  • Disk Drive: Western Digital SE Caviar 200GB SATA 7200RPM
  • Optical Drive: LITE-ON DVD-RW LDW-411S
  • PSU: OCZ StealthXStream 500W
  • Operating System: Windows XP Pro SP3 32-bit

VGA Cooler Results

The stock cooler on the 9800GT was tested for a reference point and I'm sure you are all aware that stock coolers don't always perform too well and this one is no exception, I also tested the MK-13 without any fans to see how well it might perform in passive mode. Also included are the results from the Xigmatek Bifrost cooler tested recently.


As you can see from the results the ProlimaTech MK-13 VGA cooler is a great performer with a very respectable idle temperature of 37ºC, even with no fans it easily out performs the stock cooler on the 9800GT. The ProlimaTech MK-13 VGA cooler beats the Xigmatek Bifrost by 6ºC under load with stock clocks and performs the same as the Bifrost when it the 9800GT is overclocked. No matter how far I pushed the overclocks the temperature wouldn't go above 52ºC, and I'm sure that with higher airflow the temps could have possibly fallen by a few degrees.

Hi there, a big downer as far as I'm concerned that you barely mention is how much space a cooler (+fans) takes up. It looks from your pic of it installed that it takes up at least 3, possibly 4 slots!! That's a big deal.

Also, although you test the MK13 passive, you don't test the Xigmatek passive. Even though the MK13 beats it with active cooling, you shouldn't assume it will passive. And even if it does, would be interesting to know if Xigmatek can effectively passive cool too.

Alright lets see
first 2 slots
the 3
now 4 ?
whats next ? 7 slots ?
as long as i m concerned they can keep it for themselves
they didnt understand we need a better cooling solution with no more than 2 slots like the original .
Almost all peple r not willing to sacrifice a whole pc for a vga heatsink .
I surely am not !

You should visit the ProlimaTech website, and contact them regarding this question. They would be the best person to ask.

The performance increase over what I have doesn't merit the extra $28 (best price) IMHO.
With 2 120mm fans it has a delta of about 17-18 and 28-29° respectively based on your reported case temp of 23-24°
FurMark 1.6 (same procedure)
BFG 8800GT OC2 675 975 1674 (effectively identical card)
Arctic Cooling Accelero S1 rev2 (best price $22)
1x 120mm 1200rpm 40cfm fan
case temp 28-29° (calibrated thermocouple)
Idle 51° (22-23°)
Load 66° (37-38°)
Maybe if it was tested on something more powerful than a 9800GT to better reflect it potential I might feel differently.
I am a fan of their CPU coolers though I have the Prolimatech Megahalem and it is awesome

True and i agree i myself wont scarify more than one slot for fitting the vga onto it and another slots for VGA cooling.. thts it. Boss i even have to fit in other pc components onto it like sound card, tv tunercard and other future cards that will b made available along with my old pci cards. Dont forget we have only 7 slots. i really wish if mother board manufactures give us more room for those additional slots possibly upto 10 with 2-3pci, 4 pci-e x1 & rest x16 slots
