Performance per watt of modern systems has greatly improved; many more computations can be carried out with a given power consumption than was possible with the integrated circuits of the 1980s and 1990s. Recent supercomputer projects such as Blue Gene rely on air cooling, which reduces cost, complexity, and size of systems compared to liquid cooling. Fans are used when natural convection is insufficient to remove heat. Fans may be fitted to the computer case or attached to CPUs, GPUs, chipsets, power supply units (PSUs), hard drives, or as cards plugged into an expansion slot. Common fan sizes include 40, 60, 80, 92, 120, and 140 mm. 200, 230, 250 and 300 mm fans are sometimes used in high-performance personal computers. A computer has a certain resistance to air flowing through the chassis and components. This is the sum of all the smaller impediments to air flow, such as the inlet and outlet openings, air filters, internal chassis, and electronic components.

Courteous staff and very fair on pricing. They set me up with a perfect machine. Very professional, knowledgeable and friendly people. Just a shoutout to anyone who needs a computer repaired or replaced. These people are fantastic! I ordered a new custom computer and couldn’t be more pleased with how it turned out. They answered my many questions and concerns. Will definitely patronize this place again! They’re in the Outback Shopping Center, just a little south of Outback Steakhouse. Thanks, Steve, Sean,and Jerry (I was in there so often I got to know all their names. Steve was awesome and fixed my computer problem in no time. Will definitely use them in the future! Knowledgeable and quick service. Got my computer issues solved quickly! Traded in my 2014 MacBook Pro for a reconditioned 2015 MBP with more storage with full conversion and transfer of files in a 24 hour weekend turnaround!
Upgrading your computer's hardware isn't the only way to feel like you have a new machine. A new monitor can go a long way towards making your computer more fun to use and more functional. At the same time, there are hundreds of displays out there by dozens of companies at all different price points. Still, we're only interested in the best, and here's a look at the top five, based on your nominations. Earlier in the week we asked you to nominate the computer monitors you thought were the best. You came up with dozens of great monitor suggestions, but we only have room for the top five. Every good computer needs a good monitor, and this week we want to know which monitors you think… The polls are closed and the votes are counted! To see which of the top five you crowned as the winner, head over to our weekly hive-five followup post to see and discuss the champion!
Tandy Corporation announced the TRS-80 Color Computer in July 1980 to compete with the inexpensive and popular Commodore VIC-20. The Color Computer is a completely different design than the Zilog Z80-based TRS-80 models. The TRS-80 Color Computer derives from an "experimental videotext project by the Kentucky Cooperative Extension Service and the University of Kentucky College of Agriculture" in 1977. Motorola Semiconductor of Austin, Texas, won the contract for the user terminals and Tandy's Computer Division joined later to manufacture the terminals. The initial goal of this project, called "Green Thumb", was to create a low cost Videotex terminal for farmers, ranchers, and others in the agricultural industry. This terminal would connect to a phone line and an ordinary color television and allow the user access to near-real-time information useful to their day-to-day operations on the farm. Motorola's MC6847 Video Display Generator (VDG) chip was released about the time the joint venture started. The 1978 prototype "Green Thumb" terminal used the MC6847 and the Motorola 6809 microprocessor.
