Today I've got the last of three CPU coolers that Kingwin has sent me over for review, the RVT-12025D, and this thing is huge.
The RVT-12025D offers decent cooling performance but not what you might expect from such a large cooler, you won't be breaking any records with this cooler. It's built to be silent and keep your CPU cool, and that it does well. Installation though can be tricky, and downright difficult actually…

A Better Look at Things
:
If you read my reviews of the other two Kingwin coolers then the package for the 12025D should look very familiar, all three have very similar packaging. There's a window on the front where you can glimpse the cooler itself, and the rest of the box is filled with more pictures and information.
Unpacking the 12025D we find the cooler itself, LGA775 mounting brackets, screws, white thermal compound and a Molex to 3Pin adapter.
The Kingwin Revolution RVT-12025D is a beast of a CPU cooler, it's not only wide but tall as well. Even though it's large it's surprisingly lightweight for its size. There's four copper heatpipes running up through the aluminum fins cooled by a 120mm fan.
the fan is held in place by anti-vibration mounts, these work well, and have become popular on many CPU coolers.
Here's a few shots looking at the cooler from the bottom, you can see most of the height comes from the heatpipes, the fin section is basically held up by the pipes themselves, so care should be taken when handling and installing as not to bend the pipes and possibly impede performance of the cooler.
The base appears flat and has a semi-finished look to it, the heatpipes directly touch your CPU to help improve cooling performance.
Here's a closer look at the included accessories, standard fare, nothing special really…
Installation, Testing and Comparison
Before you can install it in your system you'll need to attach the LGA775 mounting brackets, this is very easy to do, just two screws are needed.
The actual installation on my system was a real pain, no you don't have to remove the motherboard, but it could make things easier if you do. I removed both the power supply and my video card because I could not get at the locks on the base of the cooler to secure it in place. It's just so large and wide that you cannot get in there with your hands to access the push-pins so something has to come out to complete the installation process. Other than that I ran into no other clearance issues at all, smaller cases of cases that have funnel style vents in them might have a problem since it is so large, you're not going to put the RVT-12025D CPU Cooler in a small case.
The Kingwin Revolution RVT-12025D was installed in my secondary testing system which consists of:
Gigabyte GA33M-DSR2 motherboard (Review HERE )
Intel C2D6420 / Intel C2Q6600
2gigs Crucial Ballistix Tracer PC2-8500 Ram (Review HERE )
Connect3d X1800GTO Video Card
1x HDD
1x DVD/RW
Ultra X-3 800Watt PSU (Review HERE )
1x120mm Intake fan
1x120mm Exhaust fan
Housed in a Thermaltake Matrix VX case (Review HERE )
Now onto the testing to see just how well the Kingwin Revolution RVT-12025D CPU Cooler performs and how it compares when put up against other CPU coolers.
Ambient temperature during all testing was 19C (+/- .3C).
To achieve load I used Orthos Stress prime and used the latest version of CoreTemp to log results, then they were average out to get the data in the charts.
Testing on the C2Q6600 was the same except two instances of Orthos Stress Prime were run with Affinity set to the separate cores to achieve 100% load on the CPU. All four temps were averaged out to get one overall temperature as shown in the charts.
All tests were run several times over the course of 5 days then averaged out.
The first set of tests were run using the included white thermal compound, the rest of the tests were run using Arctic Cooling MX-2 Thermal Compound to insure good comparison results with the other coolers.
Since I just tested both the RVT-9225 and RVT-12025, I figured I'd include it in the stock thermal compound chart for comparison sake.
You can see that even though it's very large, it doesn't perform quite as good as the other Kingwin coolers I've tested.
Onto testing with my Intel C2D6420, first up is with the fan connected to the CPU header or PWM controlled.
In comparison with the others the 12025D shows decent performance.
Next up we have testing with the fan connected to the Molex, or running at full rated speed of 1500RPM.
Here again we see very good performance overall from the 12025D. The fan is very quiet even running at full speed, virtually silent.
The final test on the C2D is with no fan:
The 12025D works very well to cool the C2D when there is no fan, you could easily run your system silent using this cooler and have safe temperatures for you CPU.
Now we have testing we my C2Q6600, here we see very different results in performance of this cooler, first test is with the fan connected to the CPU header:
Relatively high temps, but still well within the safe zone, your CPU will be cool but you won't break any records with it.
Next up is with the fan connected to the Molex:
With the fan running at full speed we only see a 1 degree drop in temperature over running the fan connected to the CPU header, not much of an improvement at all…
and finally we have testing on the C2Q6600 with no fan at all:
meh.. temps are nothing spectacular..
Overall the Kingwin 12025D is an average CPU cooler, it will keep your CPU cool but don't expect anything amazing in the way of temperatures. As you can see from my testing it is much better suited to be used with the C2D.
I'm thinking though if we throw a higher RPM/CFM fan on this cooler we would see much better results, yes silence is nice, but sometimes performance is sacrificed in favor of silence as we see here.
Summary:
The Kingwin RVT-12025D CPU cooler is average at best, when compared to others out there today it falls about the middle in performance.
The 12025D works and will keep your CPU cool, you won't have to worry about overheating, and it's silent as well.
The major drawback to this cooler is the size, it's huge making it very difficult to install.
DragonSteelMods gives the Kingwin Revolution RVT-12025D CPU Cooler a 4 out of 5 score.
Pros:
-Well made
-Lightweight
-Quiet
-Good performance on C2D
-Inexpensive
Cons:
-Very large
-Installation can be difficult/tricky
-Might not fit in some cases
I would like to thank Kingwin for the chance to review the Revolution RVT-12025D CPU Cooler and for their continued support of DSM.
