JetArt SL1800 Slim CPU Cooler


Ok, yesterday we looked at the JetArt SL1600 Slim CPU Cooler, today we have what might be considered its big brother, the SL1800 Slim CPU Cooler. The SL1800 is basically the same as the SL1600 except thicker, and thus has a bit better performance. I could have combined both coolers into one review, but I felt that they deserved their own separate coverage because they are just such great little coolers. So read on to see the performance of the SL1800 compared to the others on the test bench…

So, the packaging is the same as the SL1600 Slim CPU Cooler, nothing flashy, it is really made for OEMs and 1U applications.

The SL1800 was packaged very well with lots of bubble wrap and plastic padding.

Included with the SL1800 is the mounting bracket for an LGA775 motherboard, thermal grease and spring tension screws for mounting.

The SL1800 is still very thin in comparison to other CPU coolers out there, the fan is only 10mm thick while the heatsink itself is only 23.5mm thick, the entire cooler is only 36mm in height. So it is very small, and will fit any case setup.

The one thing that makes the SL1800 special is that it is solid cooper, being solid makes it optimum for thermal transfer and will keep your CPU cooler than aluminum or a combination will. The SL1800 comes with a plastic protective film over the base of the heatsink.

The actual base of the SL1800 is very well done, a nice finish, not quite mirror but still very flat and shiny.

Here are some comparison shots of the SL1800 and the SL1600, the SL1800 is on the left.


You can see the SL1800 looks almost twice the size as the SL1600. The SL1600 cooled very good compared to the stock Intel CPU cooler, so I expect the SL1800 to cool even better.

Installation, Testing and Comparison

Installation is fairly easy, here again you need to take the motherboard out of the case so it does take a bit of time and patience to install the SL1800. The total time to install just the SL1800 is about five minutes, but installing everything else back in your case is what will take the time, should be about 30 minutes or so, depending on how proficient you are. With both installs of the SL1800 and the SL1600, I did find it was a tight fit on my motherboard, but that is only because ASUS stuck a heatsink right next to the CPU socket, and this seems to get in the way of most CPU coolers I have installed on this board.

And here is the SL1800 back in the case with everything installed again.

Ok, that’s out of the way, let’s get onto testing. For testing I am using my ASUS P5WD2-E Premium motherboard with an Intel P4 Cedar Mill 631 CPU running at stock of 3.0Ghz. Ambient temperature during testing was approximately 25C, idle temperature was measured after letting the system sit idle for approximately 30 minutes, while load was achieved running Prime 95 for the same time duration. Of course I also have the temps of the SL1600 in the chart as well, so we can get a good idea of just how they fair against each other.

Well as can be expected the SL1800 did perform better than the SL1600. The SL1800 scores very well when compared to the performance coolers from CoolerMaster and Thermalright, especially at idle, even at load it comes close to the temps of the Thermalright SI-128 CPU Cooler.

The sound level of the SL1800 is low compared to the Intel Stock cooler, and is actually fairly quiet even at load. I can live with it, overall it doesn’t add too much noise to the sound level of your case.

The SL1800 would be perfect for an SFF case or possibly even and HTPC case.

As you can see the SL1800 performed very well, we’ve learned from reviewing the SL1600 and the SL1800 that 1U or OEM products can perform just as well in a consumer setup and offer other options as well, like uses for SFF systems where space is at a minimum. I really like the looks of the JetArt SL1800 and SL1600 CPU coolers, they are quiet and they perform well.

DragonSteelMods gives the JetArt SL1800 Slim CPU Cooler a 5 out of 5 score
