ASUS Announces First Hardware Overclocking Device

ASUS has recently announced the world's first hardware real-time overclocking device for graphics cards, the OC Gear. Paired with their EN8600GT OC GEAR/HTDP/256M (which features -1 memory modules), the OC Gear is aimed to provide the ultimate overclocking experience.

The OC Gear sports an easy-to-read LED display that displays graphics card information such as GPU temperature and current FPS in real-time. All it takes is a simple twist of a knob to adjust such settings as GPU clock frequency and fan speed.

The OC Gear is an easy-to-install front panel device, requiring only a 4-pin USB connector to be plugged into the motherboard to provide power and information.

The 8600GT paired with the OC Gear is not without its own special features. Aside from the -1 memory modules, it sports a different heatsink from the reference design that has 25% more surface area, lowering temperatures by up to 14ºC.

The EN8600GT OC Gear also includes an array of software, including
Splendid, Gamer OSD, VideoSecurity Online, and SmartDoctor. This package gives and enhanced visual and gaming experience plus extra security.

Hey :)

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:

your temps seem fine tbh
i am guessing here but when you put the case side on its directing the air flow from your case fans over the heatsink
also temps can only be above room temperature due to the fact that the air can only cool the heatsink down to the same temperature cooler air = cooler temps

04-07-2007, 10:00:31

Are you running stock or overclocked?

And what case are you using?

It's not really the temperatures of the CPU that concern me, as you say they are fine. It's just that the temperatures didn't drop or raise when the fan was enabled or disabled, ie. blocking heat away from it instead of the warmer air from the CPU lingering. It's more so the motherboard chipset temp, which hasn't changed when adding an aftermarket cooler WITH a fan. Room temp currently is 29c.

Stock again since I was fitting a new heatsink so I removed the overclock for the moment. The 36c/35c is with CPU @ 1.6Ghz (Speedstep) instead of the normal 2.13Ghz. The case is the Antec P180.

Ahh yeah. You don't need a fan on the HS with the ninja + P180. The two exhaust fans take care of it.

As for the NB id say that the little Akasa one (if its the one im thinking of) isn't that much better than the stock. On the other hand it might be as much heat as the chip can dissipate itself.

04-07-2007, 10:37:20

Thanks for the note on the Ninja + P180, guess I can take that fan off :)

Also just removed the connector for the Akasa chipset cooler's fan, so it's fanless and the temperatures didn't move. I thought that the temperature might actually be coming from the Southbridge so I've touched it and apparantly it's 42c but it doesn't feel that hot to touch. Really confused over the motherboard temperature reading. I would be as worried, but this is with no overclock and idle. From what I'm aware the temperatures will get higher with an overclock on the South or Northbridge and of course when gaming, so the motherboard might be hittig 55c under load which is rather high.

What are you getting your reading form?

Speedfan and Everest, both reporting exactly the same motherboard temperature.
