Since the introduction of DirectX10 GPUs, quad core processors, and chipsets full of features but also incredibly hot and sucking a lot of power up PSU wattage has grown in leaps and bounds from the high but occasionally necessary 500W to the ludicrous 1200 and 1300W PSUs. That said even people with very high-end PCs don't need that much power. Today we have a PSU to look at from a somewhat less known company, BGears and their 650W Tarantula PSU.

Here are the features for the power supply.

- 13.5 CM fan for excellent airflow and quiet operation
- Oversized Heatsink for better heat absorption
- SmartFlex Modular Cable Management, great for SFF cases
- PCI Express, SLi and Dual Core CPU Ready
- EPS 12V and ATX12V Version 2.2 Compliant
- Active PFC for better power efficiency
- Sleeved cabling for a tidier look
- Green Power for extreme low power usage in standby mode
- High Efficiency of up to 86%
- Universal AC input 115~230V automatically scans and detects the correct voltage

Inside the box the PSU is neatly packed and features a gun metal black coloring. It's fairly standard size for a PSU of this wattage. Inside the package you'll find all the modular cables that the power supply comes with. These are different from other modular devices that you might be accustomed to because instead of ports the cables connect to other smaller cables on the power supply. This means they are quite long and might be a little bit more secure than using ports. The modular cables include a PCI-E 8-pin power adapter, two modular molex cable adapters, and two modular SATA cables. Included onboard are the 24-pin adapter, 8-pin CPU power connection, another PCI-E 6-pin power adapter, and one each of molex and SATA able. As with other power supplies the main power cables come straight out from the PSU.

For cooling the PSU uses a larger than normal 135mm fan and in testing ran quite cool overall and also was quiet. The Tarantula is rated for 86% efficiency which is good although not the best out there. Other features the Tarantula sports includes an oversized heatsink, auto fan speed control, and Green Power and RoHS compliant.

When thinking of buying a new heatsink the first thing that comes to mind isn't usually a new one for your video card but rather your processor. But of course there are quite a number of people who look for the performance edge wherever they can get it and an add on VGA cooler can be quite helpful in that respect. Today we have one to look at from Arctic Cooling, the Accelero S1 Revision 2 cooler with Turbo Module fans.

Here are the specs.

Heat Sink: 138(L) x 215(W) x 33(H) mm
Heat pipe: 6 mm x 4
Weight: 268 g
Accessories: 2 Voltage Regulator Heat Spreaders
8 Memory Heat Sinks
Warranty: 6 Years

Application:
ATI:
Radeon HD 38xx series, 36xx series, 2600, 2400, X1950, X1900, X1800, X1650, X1600, X1550, X1300 series
nVIDIA:
GeForce 9600 GT, 8800GTS(G92), 8800GT, 8600, 8500, 8400, 7950GT, 7900, 7800, 7600, 7300, 6800, 6600 series (except 7X00 GS AGP)

The card comes packaged in a rectangular box which is just the right size for a card this large, meaning not unnecessarily big. Rectangular in shape it features Call of Juarez on the box although we didn't see it in our bundle. Inside the card is packed nicely in Styrofoam with a fairly typical hardware bundle. DVI-to-VGA adapter, DVI-to-HDMI adapter, molex to PCI-Express power adapter, HDTV cable, and S-video cable. No extra software bundle is included. Arctic Cooing also included their Turbo Module coolers as well which fit easily into the Accelero. Here are the specs on the fan.

• Dual High Performance Fans
• Enhance Cooling Performance
• Extremely Quiet
• High Reliability
• Easy Installation
• Low Weight
• Long Lifetime
• 6 Years Warranty

Installation takes a little time and patience but isn't extraordinarily hard. With our GeForce 9600 GT video card we began by removing all the screws on the back of the card. That is quite simple to do and afterwards the stock heatsink comes off quite easily. You'll then want to remove the backs of all the memory heatsink so they can affix themselves to the memory modules on the graphics cards. After that,  remove the sticky tag on the main GPU heatsink and put the spacers on the holes to screw into. There are both "A" and "B" holes depending on the graphics card you are using. Lining up these four holes with the GPU is a little bit tricky but once you have it lined up you can start screwing in the screws. If all you want is a passive heatsink at this point you are done.

We went further though and installed the Turbo Module coolers. This is a little bit harder and you'll need to use a flat head screwdriver to push open the aluminum fins to stick the fans into so it clips into the fan and remains steady. You'll hide the power cord in there as well so it doesn't get in the way of the fans. After this attached the power cord on the fans to one matching on your motherboard and you're ready to go.

Let's move onto testing.

Cooler Master have been around in the PC industry for quite some time producing fans, cases, and power supplies that often show up in OEMs and retailers. More often than not we're a fan of their cases and PSUs but today we'll be looking at one of their heatsink/fan combinations the Coolermaster Hyper TX 2.

The Hyper TX 2 sits towards the lower-end of the coolers coming up at $25 around Newegg. While this is more expensive than a stock cooler it's about $20-35 away from the higher-end coolers. The packaging on the cooler is very minimal with the heatsink covered in plastic with some instructions and accessories included with it.

The Hyper TX 2 is ready to go out of the box for Socket 775 systems featuring clip brackets and if you need it for a Socket AM2/AM2+ system it the clip fits in between the heatsink and is easy to install after removing the 775 clips. As with stock Intel heatsinks it comes with thermal grease already on the heatsink.

A fan is mounted on the outside of the cooler bringing it to a size of 108.3 x 123.7 x 136.5 and moves at 1800RPM and is rated for 22dBA. Fan life expectancy 40,000 hours with a 3-pin connector and is mounted onto a plastic shield covering the top and back of the heatsink. The heatsink is one made of aluminum fins and has a copper base with three heatpipes. Installation was a breeze on both a Socket 775 motherboard and also Socket AM2/AM2+.
