The Cooling Performance of the Green Reactor 3D Test PC

July 13th, 2010 · 11 Comments · Other S3D Tech


As I’ve mentioned a few days ago the new Green Reactor 3D Test PC is ready and functioning with just a few minor things been tweaked and changed/fixed, mostly related to the appearance and not the functionality. And of course the good question that arises here is how well does the custom liquid cooling does its job in keeping the CPU and the VGA cool enough, so here are the temperatures of both. The two components are being cooled in a single loop with the water first going through the CPU and then through the GPU water block. For really stressing both main components I’m using LinX for the CPU and FurMark for the GPU running with everything to the max and even 32xAA active to really push the video card to the limit…



The processor being currently used is Intel Core i5 750, a quad-core CPU with idle temperature of about 34 degrees Celsius and it goes to around 50 degrees Celsius in about 20 minutes and stays at that temperature after that. This is with an ambient temperature of about 30 degrees Celsius and the fans not running at 100%, but at 60% instead to be really quiet, which still providing really good airflow and cooling performance.



The idle temperature of the GPU is around 42 degrees Celsius with 30 ambient temperature in in about an hour of serious load with FurMark its temperature rises up to 71-72 degrees Celsius max and pretty much stays there after that. If the cooling liquid did not go first through the CPU block and then through the GPU block the temperature could’ve been lower, but even this way it is still very good. Silent operation and around 25 degrees lower temperature as compared to the loud air cooling and the high working temperatures reached with the same level of high load otherwise. If staying at default working frequencies the voltage of the CPU could be further lowered while the card continues to operate flawlessly, up to something like 0.86V the temperature drops with about 10 degrees under maximum load of the GPU, and that is something that you should do if you do not intend to overclock the video card.

Building Process of the Water Cooled Green Reactor 3D Test PC

July 8th, 2010 · 1 Comment · Other S3D Tech


Somewhere along the idea to upgrade the old 3D Test PC with water cooling (details for that project are available here) I got the idea to leave the other computer as a dedicated AMD/ATI test system and build a completely new 3D test PC for 3D Vision, again with water cooling of course. So practically you can say I’ve started working on the two projects at the same time, but the system that just needed the upgrade was finished much faster than the completely new system. The reason for that being that I wanted to make everything the right way, choose the components carefully and apply a matching custom water cooling and the end product to be really good looking and performing as fast as possible in order to have the ultimate 3D Test PC for testing stereo 3D content and of course to be able to game comfortably enough in stereo 3D with the 3D Vision. Now that there are just some minor unexpected details left to work out…



The photos above are from the almost finished Green Reactor PC with a lot of small finishing details only left to be done, so it is pretty much ready and working at this point of time. I’ll just update with some more pictures when all the finishing touches are ready… So stay tuned for more information and photos.

Upgrading my 3D AMD Test PC with Koolance Exos 2.5 Water Cooling

July 4th, 2010 · 8 Comments · Other S3D Tech

A few weeks ago I had the good idea to upgrade my 3D test PC with water cooling, because the summer was coming and the temperatures were starting to rise. And anyone with a high-end video card knows that with high ambient temperatures and heavy load because of playing demanding games, especially in stereo 3D mode. And unfortunately the high temperatures come with more noise coming from the air cooling, so going to water to get better cooling and quiet computer seems like a good idea, don’t you think?


And because the original idea was just to add water cooling for the CPU and the GPU, I started with looking for a good external unit that has the water pump, cooling radiator and the fans outside of the case. The reason for that being that the Chieftec case I had did not have a lot of space inside for installing a bigger radiator (just one 120mm on the back and that is just not enough). I was researching different solutions, including passive convection radiators, water towers etc, and the final decision was to go for Koolance’s external Exos unit – the 2.5 model that has triple 120mm fans and a 3×120 radiator. The idea with that was to get the unit run at reduced capabilities to achieve silent operation while at the same time to have more than enough cooling power to keep the hardware at low temperatures even after long hours of maximum load. Another important reason for choosing that was external water cooling unit was because its size was just about the same as the top of the Chieftec case I used, so the combination seemed just perfect, making the whole computer still quite compact and easy to move, unlike with some other external water cooling solutions I’ve seen.

Of course the Koolance Exos 2.5 unit contained all the external parts for the water cooling system – the fans, radiator, pump and reservoir, but the rest in the form of fittings, water blocks and tubing needed to be decided on as it is completely custom. So I’ve ordered all the needed parts and started building the water cooling upgrade, but somewhere during that process I’ve also decided to go for building a second high-end system with a completely custom water cooling solution starting by choosing a nice and big enough case, but the worklog for that will come after finishing with this one.



So the ATI/AMD-based 3D test computer was ready to finally get the more serious attention that it needed for quite some time, and the water cooling upgrade was just an excuse to do that. And so the that was the general idea upfront, but meanwhile the things did not turn out quite as good as expected…



Here is how the finished setup looks like, ready for the stage when the PC is powered up for a first time with the new water cooling installed and ready for some tests to be done, so that the effectiveness of the cooling can be judged.



And here are the end results after installing the new water cooling – much cooler operation temperatures even under heavy load and somewhat more silent operation of the computer because of the water cooling, or that is what you should normally expect to get. After a bit more than 1 hour of running OCCT and Furmark with heavy settings and creating a high load on the CPU and the GPU the temperatures go like this: around 41 degrees Celsius for the CPU and average of 45-46 degrees Celsius for each of the GPUs on the video card. Of course this is on their default frequencies, so there is some room for good overclocking of the system, but that I’ve left for a bit later time since I had a second computer to build from the scratch and this second system was much more complicated to plan and build and you’ll soon be able to see why.

The idea for this computer is to now go as a dedicated solution for testing with the iZ3D solution with their 3D monitor, and the Nvidia video card that was a second option inside the Chieftec case is now gone. Instead I built a new computer that is dedicated to testing with 3D Vision and Fermi, but more about that will be available very soon. So back to the AMD/ATI system – this is just the very short idea about the project, there is much more detailed one with a lot of photos and more information of the build process and how things turned out at the end and if you are interested in that you can take a look at the link below to the topic of the forum where all the details are published ;)
