Just recently got this Scythe Ninja to replace a Arctic Freezer 7 Pro to help some with temps and also a replacement northbridge heatsink (Akasa AK-120), as my PC / room is quite hot all the time. Was testing some fan placements in the PC recently and noticed some odd things.
Firstly just to note, I replaced the stock heatsink on a 965P-S3 for the Northbridge with an Akasa AK120, which has done zip for the temperatures, it's near enough the same as the stock heat sink give or take 2c, which I can't understand because the stock one is rubbish, and the Akasa one has a 40mm fan on it. The temperature idle hovers around 35c. Now, what I don't get however, is if I take the side of a case off, the temps of this northbridge whether the Akasa Ak-120 was attached or the stock heatsink, the temps go up to 43c idle in about 15 seconds. As soon as the case side is put back on, temps go down again to 35c. So I'm very confused about that :eh:
Next is the Scythe Ninja. I strapped an Antec 120mm TriCool fan to the Scythe Ninja, which has a little switch to control the fan speed/cfm/noise. I tried flicking the setting to check out some temperature readings after leaving it 3 minutes on the specificed setting, and it read (these are idle temps):
Low setting: 36c / 35c
Med setting: 36c / 35c
High setting: 35c / 35c
OFF (ie. passive): 36c / 36c
So basically if I don't strap a fan to the Scythe Ninja and leave it passively cooling and just using the case fans to suck air, it gets near enough the same idle scoring after a few minutes of testing as with an Antec TriCool 120mm strapped to it at any setting. I tested these temperatures from Speedfan, TAT, Core Temp and Everest in case some of the programs were reporting the temperatures in correctly. So I don't really understand why the fan strapped to it pushing apparantly 72 CFM compared to 0 CFM doesn't pretty much nothing :eh:
