This review is from: G-sensor GS8000L HD 1080P Car DVR Vehicle Camera Video Recorder Dash Cam
Pros: This device works as a camera and performs the tasks that it was advertised to do. The item is priced very well.
Cons: Considering the price, I wasn't really expecting much. I figured I'd give it a shot since I didn't have much to lose.
There are a few problems that I have with this camera unit.
- The camera mount doesn't seem to be very firm. I have to re-adjust it and tighten it every so often.
- The image quality is poor. I set it to record at 1080, however, when I played it back, it looked like it was recorded at a low resolution and just up-scaled.
- The camera sensor suffers from rolling shutter (jello effect). It does not handle vibrations very well, and the rolling shutter problem is very noticeable when you have your windshield wipers go back and forth.
- The loop recording doesn't seem to work properly. This camera has always stopped recording and stating that the memory card is full. I have to constantly format the card and have it start recording again.
Other Thoughts: If you have a few dollars to spare, then you can buy this camera but don't expect anything great. It's better than not having any video camera in your car so I suppose it's worth purchasing. However, if you are serious about quality, such as being able to read a license plate, check out the systems from FineVu or BlackVue.READ FULL REVIEW
This review is from: Noctua NH-U12DO A3 for AMD Opteron workstations and Servers CPU Cooler
Pros: The fans run very quietly with this. If you end up hooking it up to a source that doesn't offer PWM speed control, there are some connectors with in-line resistors that will lower the speed of the fan so you can run it more quietly.
I chose Noctua because of the great things I've read about them in computer magazines and also from using them in a build I did for my brother. I was impressed with how cool and quiet his air-cooled system was, so I decided to use Noctua for my server upgrade.
Everything is included, such as heatsink thermal compound, hex wrench, C32 and G34 brackets.
Cons: Too tall for a 4U case. Removing the fans from the heatsink can be difficult, as I've had to do in order to return it.
Other Thoughts: Newegg lists this item as being smaller with the fan attached than without the fan, which I found out is not true. Also, Newegg lists its dimensions (With Fan: 6.1" x 4.96" x 2.56") out of order. Normally, dimensions are LxWXH but the height is actually over 6.2" according to Noctua's site. The heatsink/fan work great and Newegg's problem with dimensions is no fault of the product so I will not knock the rating down. However, keep in mind that this fan is just a bit too tall to fit into a 4U case. I was able to get it to fit with the lid sitting on the heatsink, but couldn't close it. Ended up returning it for the NH-U9DO.
Also, ensure that your motherboard is compatible with 3-pin fans. My motherboard, the ASUS KCMA-D8 requires a jumper setting to be changed to use 3-pin fans.
This review is from: Noctua NH-U9DO A3 AMD Opteron, 4 Dual Heat-pipe SSO Bearing Quiet CPU Cooler
Pros: The size of this heatsink/fan makes it ideal for a 4U server. I'm using this on an Opteron 4386 in a ASUS KCMA-D8 motherboard and it is the right size for it. It is also really quiet, especially compared to the louder case fans that came with my server case.
Very simple to install as well. Comes with everything you need, such as wrench and thermal paste.
Cons: When using the L-shaped hex wrench vertically, the handle is really small and uncomfortable to turn. I ended up holding the wrench with some vice grips and this made it a lot easier.
Other Thoughts: I read some of the bad reviews about getting the screws in for the brackets and can possibly see where that might be difficult to get started if you have larger fingers. I'd say I have average to slender fingers and had no problems with the 4 screws that attach the brackets to the heatsink.
On an 8 core Opteron 4386, I'm averaging about 104 degrees F with light loads (running 5 virtual machines).
