Performance and Test Results
With the Test Spec and Methodology covered to granular detail, time to move to the meat of the review and cover performance. But not so fast, a short lead in is required. If you read the first page then you know the Titan Fenrir comes bundled with a fan, and only supports a single fan, so we have testing with the stock fan and our trusty Scythe Gentle Typhoon 1850. Further delaying you from eyeing the performance data, some quick shots of our best performing orientation as discovered in pretesting and a photo of the TIM print from one of the mounts during testing. I do not recall which test run the TIM photo was taken from as I just pulled the cooler off for another mount and snapped the photo quick.
If you are familiar with the EVGA X58 Classified, you know the orientation of the CPU socket, if not then this orientation is what I call “Fan parallel to socket arm” which is the best performing orientation for the Fenrir on our bench and will be used for all logged test runs. For this photo I left the RAM out of the board so you can just catch a glimpse of the hold down plate, but you can see the fan does not interfere with closest RAM slot. Admittedly, the TIM spread does look a little odd but this was the norm on all the mounts even though it does appear to be off-center toward the top edge. For all of our air cooler testing, we set aside the TIM that comes with the cooler and use Arctic Cooling MX-3 for all tests. Those of you who have worked with MX-3 before you know firsthand of the consistency which I can only describe as an oily, clay like combination. When I first opened a tube and started using MX-3, I thought maybe I got a bad batch… but no, each tube had the same consistency. For more info on Arctic Cooling MX-3, check out our TIM Round-Up V1.1.
Kicking us off, we have the stock fan at full speed that comes in a little over 2300RPM averaged for all three mounts. The stock fan keeps our toasty 920 D0 with 1.275V Vcore under 70C with a 4-core average of 68.52C. The quick and easy mount system proved itself to be quite consistent as well, with a tremendously low variance of 0.08C for all three mounts or I am captain consistent when it comes to mounting air coolers, but I think the mount system is the reason for the low variance.
I mentioned the stock fans poor scaling when undervolting on the first page, but as you can see we only have one tested speed with the stock fan. I was hoping to have more tests with the stock fan, but stability became elusive as we undervolted the fan bringing the RPM down to the mid 1000’s. Quite unfortunate for a PWM fan to say the least.
With the stock fan tests ending a little earlier than we thought, it is time to move on the common fan tests. First off, we have the GT-1850 at full RPM in push configuration. Surprising once again, we see our core average temps come in slightly higher than our stock fan. With the Gentle Typhoon at full speed, the Fenrir comes in with a core average of 68.70C. For these three mounts, we did increase our mount variance as well, but still a very acceptable 0.44C. Even with the great airflow and static pressure ratings for the Gentle Typhoon’s, the Fenrir is just asking for more airflow.
Slowing the GT-1850 down to 1300RPM, we see average core temps jump a few degrees but less of a jump than I expected after the GT at full RPM results. The Titan Fenrir with a single GT-1850 at 1300RPM logs a core average of 73.48C but maintains stability for all three mounts. Holding steady once again was the mount variance, coming in at 0.56C from the highest core average on the first test to our lowest core average of the second mount.
Unfortunately, here is where we have some bad news. Our Fenrir was unable to complete a run with the Gentle Typhoon at 900RPM. I do not like seeing failed tests as much as anyone else, but our hot 920 D0 just proved to be too high of leakage for the Titan Fenrir to maintain with the slow spinning Gentle Typhoon.
We have covered all of the individual test runs with the stock Titan fan and our Gentle Typhoon, now to compare the Fenrir to our chosen comparison cooler, the Noctua NH-U12P. To reiterate from the Test Methodology, the Noctua was chosen as our lucky (or unlucky depending on how you look at it) comparison cooler since the Noctua comes with stock fans and supports dual fans which gives us the best cross comparison capabilities amongst the air coolers we test. However, for this comparison we only have the single fan data since the Fenrir can only support a single fan. Therefore, here are the single fan plotted results for both the Titan Fenrir and the Noctua NH-U12P…
With the chart above, you can see the more aggressive scaling of the Fenrir with increased airflow versus the slope of the Noctua with a single GT-1850. But also interesting to me is how close temp wise the Gentle Typhoon at full RPM is to the stock fan spinning over 2300RPM, which just goes to show how why the GT’s are so popular. Before we move on from the comparison chart, if you have a Fenrir and ready to move on from the stock fan in search for more performance, look for a quality 120x38mm fan. All indications point to unlocking more performance from the Fenrir with a beefy 120x38mm fan, that is if your ears can handle the increased noise.
With the comparison results covered, time to wrap this one up with the conclusion and final thoughts…
