A tutorial on how to fix Heat Problems

Why customize a computer: No one comes to me because I can build a computer cheaper than DELL, because I can’t. You don’t want a cookie cutter or a me-too computer (a Retail Store Computer). You may want something that is on the leading edge of technology. You may want something that’s higher quality, balanced, longer lasting, better running, and engineered to your needs. One of the most useful things that we builders can bring to the table is a well engineered cooling system. We can even design a cooling system to circumvent an unfavorable or bad environment.

The Truth About FPS

I wrote this article because I am vehemently against developers and console makers stating that 30 FPS is good enough, who are borderline lying to the everyone when they start mentioning science or numbers. The truth is, we all need a little more education about these frame rate numbers, why more is usually always better, why less can be bad, and more importantly: remove FUD. Note: I am a nobody, don't take anything you read here as a gospel. Look it up yourself. Let's start with handling where some of these numbers actually came from. Where does the magic 24 FPS in... read more

GPU and CPU power connections

INTRO & Warnings Is the connection we are making safe? A mistake can cost you a lot of money. A GPU is a “Graphics Processing Unit”, it is located in the video card. A CPU is a “Central Processing Unit”, it is located on the main board.. I, at one time had a lot of questions about there power connectors, their current rating, the cross compatibility, and what adaptors are safe to use. I did a lot of research and found conflicting answers. I looked at how reputable the source was, and how often I saw other reputable sources give the same answer. Being and electrical... read more

EVGA Hadron Air Chassis - Tips & Compatibility Guide

Quote:"Why sacrifice appearance and size when choosing a performance rig? The EVGA Hadron Mini ITX chassis was designed to not make any compromises." - Hadron Air manual The Hadron's appearance and size are the main reasons owners decide on this chassis, however it's not without some compromises. As long as you are aware of what limitations the case has, and plan your parts around it, you shouldn't run into many problems. Your choice of components is primarily limited by size. It was worth doing the extra research to find the appropriate parts, but it wasn't easy.... read more

Calculating Power Savings from a Platinum PSU

Suppose you have two power supplies , one is 80+ Bronze (85% efficient at 50% load) and one is 80+ Platinum (92% efficient at 50% load) You want to know whether it is worth it to buy the Platinum PSU over the Bronze PSU: Let the Bronze Efficiency = Efficiency 1 , or η1 for short Let the Platinum Efficiency = Efficiency 2, or η2 Let W be the wattage drawn by the components (CPU, GPU, sound card, fans, etc) Let the Difference in wattage at wall = W_diff W_diff = W/η1 - W/η2 W_diff = W(η2 -η1)/η1η2 W_diff for a 300W system and bronze and platinum PSUs =... read more

AMD Mantle, CPU Bottlenecks, CPU Limitations, and You!

Intro: I recently got into a discussion that was extremely one sided (everyone hates me) in a Mantle thread. It is no surprise, this type of thing happens all the time, but seeing as the group I talked to were primarily AMD users and because I have a blue CPU and two green GPUs, it makes it next to impossible to actually discuss things. People on both sides stick their fingers in their ears and go "lalalalalalala". This article is not for you if you are one of those types. It is quite frustrating when people throw tech buzzwords around like "bottleneck" and "VRAM... read more

AMD Fusion and the HSA Revolution: What is HSA and why it will be revolutionary

For questions, comments, discussion and news updates about HSA, please see the forum thread in AMD General [LINK] Quote:   At a time when cracks are appearing in Moore’s Law and the costs of shrinking fab processes continue to skyrocket, an industry that wants to keep accelerating compute capabilities must turn increasingly to optimizing efficiency. Ultimately, this is what GPGPU and HSA enable. By old methods, how much would a CPU need to evolve in order to facilitate a 5x performance gain? Now, such gains are possible simply through hardware and software vendors... read more

Optimal Placement for Your Rig

You've spent time and money putting together your dream build. Your masterpiece wants to be shown off. It wants room to breath. I don't know about you, but I think how and where you setup your build is as important as the parts inside it. Have you ever been to someones house and they have one of those wooden desks with the little cabinet on one side? They have their pc sitting in there struggling for air. They open up the door to put in a flash drive and you suddenly feel a blast of fire straight from hell hit you in the face. This may be exaggerating but your rig... read more

Estimating Fan requirements (draft)

CFM = 3.16 x Watts / delta_T (°F) ---> delta Celsius to delta Farenheit = multiply by 1.8 i.e. for 500W TDP system , delta temp of 20°C , estimate CFM required: CFM = 3.16 x Watts / delta_T (°F) = 3.16*500/(20°C *1.8 delta°F/delta°C) =44cfm which is easily attainable by two 120mm fans NON DESTRUCTIVE CASE MODs: Restrictive cases with front panels that are completely closed off with small vents on the side may opt for a triple 5.25" bay 120mm fan slot such as the * Scythe Kama Bay (http://www.scythe-usa.com/product/acc/008/sckb1000_detail.html) Evercool Armor would... read more
