Colossus Micro Thermal Benchmarking

philip Sept. 22, 2014

With the BitFenix Colossus Micro build complete, it was time to run benchmarks while monitoring it with a thermal camera. There were some concerns in the community that the system would burn up, but temperatures held modestly well. We did see the GPU clock throttle a bit toward the end of each benchmark however.

We're still refining the automation for these benchmarks, but once we get it all ironed out expect to see more of these for our builds. For this set, we benchmarked both 3DMark 11 and Unigine Heaven. Video output, audio, thermals, total system power draw, and a plethora of stats were monitored concurrently and stitched together with some in-house software to generate the videos and graphs below. Ambient temperature was ~25°C (77°F) throughout the tests (and ambient temp is a measurement we're now logging with the runs as well). Enjoy!

Breaking things down further, we plot out all the measurements over time:

September Build Guides

manirelli Sept. 15, 2014

Starting a new installment, here are gaming build guides for common price points. These builds take advantage of our parametric part list feature, so they should adjust automatically as part prices fluctuate through the day. Check them out and let us know what you think below or in the comments sections on the guides!

BitFenix Colossus Micro Build

philip Aug. 20, 2014

The BitFenix Colossus Micro is a perfectly practical case. However, the components we chose to put in it are not what you'd expect to see in a Micro ATX form factor. It was the perfect storm - we had both an Intel i7-4790K CPU and a Sapphire Radeon R9 295X2 video card on hand. That's right - the dual R9 290X video card with the attached closed loop cooler. The question was - can it fit? Yes! Barely.

We knew from the start we'd likely run into some fit issues. Putting two CLC radiators in such a small case was going to be problematic. Just fitting the 295X2 in the case when it also used a vertical mount power supply was tricky. Most power supplies that have enough wattage for the 295X2 are too long. Fortunately the Corsair AX860i had sufficient wattage and left roughly 1/2" of clearance for the video card. Like I mentioned - this build was not about being practical. It was all about what we could manage to squeeze into the case. I had the 295X2 on hand, so it begged to be used. For science!

BitFenix had warned me beforehand that the cable management on the Micro ATX version of the Colossus would be trickier than the mini-ITX version due to the more compact internal layout. I took that as a challenge. With custom cables it would certainly be possible to make it look cleaner, but all in all I'm happy with how it turned out.

Before anyone comments that we should have used part X instead of Y, or Q instead of Z, know that this part selection was not aimed at practicality. Different use cases prefer different part selections. Maybe you don't need an i7. Maybe you don't need 16GB of RAM. Or maybe the 295X2 is a tad more horsepower than you need to play Minecraft. I chose these parts for a couple reasons:

  • I enjoy smaller form factor builds and the associated cable management challenges.
  • The i7-4790K and Radeon R9 295X2 were already on hand (for benchmarking, the results of which hopefully everyone will see soon).
  • Because we could.

That being said, it was a challenging, but very fun build. When I have a chance to benchmark it and check the thermal performance, I'll be sure to provide a follow-up post.

More Than Building Computers

Water project in Malawi

Sometimes it's easy to get caught up in the daily tasks running this site and lose focus on the bigger picture. When I started PCPartPicker, I wanted it to be about more than just building computers, and to have an impact beyond myself, my family, and the visitors of the site. My desire was, and still is, to help people with fundamental needs that we often take for granted, such as access to clean water and sanitation.

Last week the first Charity:Water completion report arrived for a water project PCPartPicker sponsored in Malawi, Africa. Because of this project (the actual well is in the picture above), 373 people in the Chasembe community now have access to clean and safe drinking water. My heart is filled with joy hearing this news, and I wanted to share it with you because you're a part of it too.

As many of you know, PCPartPicker is supported through affiliate commissions from retailers we partner with. From the beginning we committed to donate part of our monthly earnings to charity. When you purchase components through retailer links on PCPartPicker, you're not only supporting this site - you're also supporting people like you see in the picture above. Thank you, from the bottom of my heart, for being a part of this and helping us make this happen.

Water project in Malawi

The water project in Malawi is the first of many we have sponsored through Charity:Water. Above is a map showing the GPS coordinates of the well pictured (-13.27416667, 34.0163). As the completion reports arrive, we'll keep you updated. In the meantime, you have my deepest and sincerest thanks for supporting PCPartPicker and our vision. It would not be possible without you.

$970 Gaming Build

philip June 27, 2014

The mission? A gaming build under $1000. At $970, we hit the price point with a bit of room to spare. And this build doesn't sacrifice performance - with the new Intel Devil's Canyon Core i5-4690K and an R9 280X, it has plenty of horsepower.

As an added bonus, Newegg has even created a combo using this exact set of parts!

For the color conscious, all the parts also match a black/red color scheme. (Yes, I know the power supply has a green logo - but it gets covered up by the side-walls of the PSU bay.)

Side View

MicroATX with just enough room to hold an R9 280X and a push-pull configured H80i. By building in a careful order, reaching into tight spots was minimized.

Front View

Dust Filter

The front intake fan has an easily removable dust filter. The top intake for the power supply also has a magnetically attached dust filter.

While Running

The AMP-Up family of Gigabyte motherboards have an LED-lit line on the back. This motherboard comes in red to match the red heatsinks. Our previous AMP-Up build came in green.
