It's been here a while, but when it showed up I was told it was time to change test platforms. So, it got put on the backburner with other coolers over the first few months of 2015.
2. I don't get this part.
Only the most die hard liquid cooling enthusiast could enjoy constantly checking coolant levels, topping them up, and flushing out algae growth when their coolant isn’t “toxic enough”. Regular users, including part-time enthusiasts, are better off with a system that doesn’t have evaporation holes or air exposure.
I don't know anyone who does this.[/quotemsg]I've personally owned a few coolers with vent holes. My coolers are poisoned with Ethylene Glycol and don't get algea, but I still have to top them up about once a year.
[quotemsg=15999185,0,35894]3. Some reference to the materials would have been instructive, especially the lack of mixed metals in the loop. Would also have liked to see power draw to get an idea of just how much oomph each pump had.[/quotemsg]Thanks, I finally remembered to do that with another upcoming cooler
[quotemsg=15999185,0,35894]4. One expects variations but this is completely out of line with everything I have seen before. The Swiftech H220-X is normally about twice as loud at full tilt than the D15 at full tilt and about 5C cooler than the Noc.[/quotemsg]I didn't believe the numbers myself so I rechecked the installation, the coolant, and the numbers. Second test was consistent with first. There could be an internal interface problem between the core and heat spreader though.
[quotemsg=15999185,0,35894]5. Another thing about that test that I would rethink is ... not loading the GFX card. This seems perfectly logical for testing 240mm coolers against 240mm coolers but gives air coolers a huge advantage. A properly installed OLC / CLC will have the radiator cooled by incoming ambient air and is little affected by interior case temperatures.
Definitely not so for an air cooler. One test showed 4C advantage to the H220-X over the D15 at both stock and 4.2 Ghz..... the Zalman Reserator lost by 6C in TPUs test....In another it had 2C at stock and 6C at 4.4 Ghz over the Noc. Again, one expects difference between tests but this stands out. As the others all show pretty much the same thing, I think something was amiss.[/quotemsg]But what would it do with the case? Most cases support radiators only on top, this case was chosen in part because it represents a "generic" layout. I thought the problem might be low liquid, so I checked that. I thought it might be a paste issue, so I checked that. I thought it might be a pressure issue, so I opened the side to check that too.
[quotemsg=15999185,0,35894]6. As was said before comparing the 240 mm H220-X against the 280mm Kraken is like comparing a Hyper 212 w/ 1 fan against bigger heat sinks with 2 fans. I could understand if there was no H240-X but there is. The H110 - GTX would also be nice it being one of the newest ones out there. In the H240-X review on the same site as the 2nd review referenced above, the 280 mm H240-X for example:
- 280 mm Kraken X61 lost by 5C and 10 dbA
- 360 mm Thermaltake Water 3.0 lost by 4C and 8 dbA.[/quotemsg]I have to admit the size difference slipped past me until the test was submitted. After checking the things above and writing the thing up as is, I looked at the specs and said "OMG it's a different size". Aside from the oversized Kraken, the only reason for the performance deficit compared to other coolers might be the size of the vent holes and the fan's proximity to them. I'd have flipped the fans over and put them under the cooler, if possible, but the H220X design doesn't permit this.
[quotemsg=15999185,0,35894]7. Assuming this was a test rig used before for testing .... and I'm therefore assuming fans on top were exhausting air. After switching the fans to push air into the case so that cooler outside air is used as per manufacturer's instructions, how many case fans were blowing in / blowing out during the test ?[/quotemsg]Kind of going at this question from the third degree right? I mean, I did get the thing back from my tester with numbers, check for installation issues, retest, open the case, re-test, and re-write the description. Anyway, there are 4 fans blowing in and 1 blowing out, two intakes by Swiftech design and two intakes by the case design. Opening the case was already cheating but I did it anyway just to investigate the pressure issue, as mentioned in the article. And so I'll say a second time, I think the most likely "fixable problem" was that these fans are factory configured as intakes, putting their fins in close proximity to the case's integrated fan grill.
