There has been speculation that the orientation of the pipes (vertical versus horizontal) has a "gravitational effect" on cooling effectiveness, but it isn't true - not much, anyway. Intel Core i5-2500 Quad-Core Processor 3.3 GHz 6 MB Cache LGA 1155 - BX80623I52500 161. They have a life-span of about a million years. Heatpipes were originally developed under NASA contract to cool components in space vehicles. You can acoustically deaden the duct itself and put a foam-rubber collar around the exhaust fan. It is only left to thermally control the exhaust fan to find that spot where the extra CFMs and noise don't make cooling any better. If you build a foam-board (or Lexan - whatever) duct between the exhaust side of the cooler and the exhaust fan (wherever it is - rear or top), you will improve cooler effectiveness. Much more detailed comparison of low level features of both microprocessors you will find in the CPUIDs section. If you mount it conventionally, then focus the exhaust out the rear vent. CPU: 4690K score: 921 Marks core freq: 4.2 GHz cache freg: 3.9GHz vcore voltage: 1.105 (according to MOBO and intel extreme tuning) I have the Noctua NH D-14 installed, the test maxed my heat at 57C, but prime95 (28.10 build 1)on max heat takes me up to 74C(fan fluctuates between 100 and 85 and keeps it less than 75). Detailed side by side comparison of FX-8350 vs Intel Core i5-4690K specs can be found in the Specifications section below. If you're going to mount the Noctua with broad side facing upward, then your main exhaust port should be at the computer's top vent.
To make a right choice for computer upgrading, please get familiar with the detailed technical. Intel Core i5-4690K contains 4 processing cores. Its base clock speed is 3.50 GHz, and maximum clock speed in turbo boost - 3.70 GHz. The Intel Core i5-4690K comes with 6MB of last level cache, and it fits into 88 Watt thermal envelope. The processor Intel Core i5-4690K is developed on the 22 nm technology node and architecture Devils Canyon S. This feature can temporary 'overclock' the cores to 3.9 GHz. The microprocessor has Turbo technology enabled. The effectiveness of these coolers depends on airflow up to the point where air-pressure and airflow cease to have further effect. Intel Core i5-4690K is a quad-core processor with 3.5 GHz base frequency. This processor is used in Desktop devices and can consume up to 88 watts of power.
It has 4 cores and 4 threads with clock of 3.5 GHz that can turbo clock itself to 3.9 GHz. I grind those suckers down flat and get rid of all the nickel plate on both the bottom surface of the heatsink base and the IHS. Intel Core i5-4690K is processor manufactured by Intel and launched in Q2 2014. There are opinions - some from our honored gurus - about heatsink "base-convexity," but I don't buy it.
