Ok so I got the Big Schuriken 3 RevB fresh off the US customs shelf (had to be imported because Canada isn't important enough for Scythe to sell it here).
Installation is not too terrible compared to AXP-100 FC overall, but the way the cooler is positioned around the CPU it left no space for the power cable in the case (partially because of the 25mm fan). So the only way I could really fit it into the case is by leading the power cable under the cooler. Still, there was no space for the cable to be straighten out on the way out of the case.
To resovle this I used those extra long motherboard extenders to give the cable some extra space.
Considering I already have pieces of cardboard holding the PCI-E riser in place, this power cable situation is making the build extra ghetto.
For testing I used PBO of -30, Prime95 in Maximum Heat testing and let it run for 20 minutes. The temps are obviously maxed out at 90 regardless of the cooler, but I used CPU package clock frequencies to judge by how badly it throttles.
Results (all tested with PPC-3000 25mm fan):
|Cooler||Absolute Minimum CPU Package Clock||Average CPU Package Clock|
|AXP-100 Full Copper (Exhaust)||4078.4 Mhz||4120 Mhz (went up from 4100 Mhz over time)|
|Big Schuriken 3 (Intake)||4058.8 Mhz||4072 Mhz (went down from 4120 Mhz over time)|
|Big Schuriken 3 (Exhaust)||4087.0 Mhz||4140 Mhz (pretty stable albeit with much higher variation than other 2 configs)|
So exhaust configuration is making a small dent in temps, as I already knew from working with AXP-100 FC, but when comparing Big Shuriken 3 vs AXP-100 FC, the latter takes the cake by virtue of not screwing up my case layout. There isn't that much temp performance difference to call a definite winner. With AXP-100 I can also use black nylon screws to hold the cooler, which matches the overall color scheme. But with Big Schuriken 3 I have to use those big aluminum screws.
