Is AMD heat a problem?
I am about to upgrade to an ASUS motherboard. At this stage I am after an
AMD type, the A7N8X-E Deluxe, but I am still concerned about the processor heat, which I heard is more of a problem than on a Pentium. Does anyone have any opinion on this, as far as general usage and as to what cooling should be provided, both on the processor and from the case? Are there any cases or fans I should avoid? If I get an AMD processor, can I stick with the standard fan supplied in the boxed set? I have no plans to overclock anything in the system. Thank you for any information. Henry |

IF you're not planning to overclock the stock parts will be fine.

Both the Pentium IV and the AMD Athlons produce a similar heat output. If
you are not overclocking the stock heatsink is just fine as long as you have a case fan or two. -- *****Replace 'NOSPAM' with 'btinternet' in the reply address***** "Henry Mydlarz" wrote in message u...

The only bad thing about AMD's heatsink is the noise, 60mm fan @ 5000RPM 35db, give or take a few points. AMD CPU & Heatsink Installation Guide http://tinyurl.com/3ue5 Ed Yesterday I replaced my Athlon 1700+ with a 2600+. I used the stock fan that came with the new chip. I could not use the Zalman flower heatsink I had on the 1700+ (too much heat with the 2600+) bit I am pleasantly surprised at both the low noise level of the stock fan and the fact that it has a copper core. |

The AMD chips do run a bit hotter than the equivalent Pentium chips, but only because they are doing more work per clock cycle. IOW, more work = more heat, both chips have similar efficiency. The hottest AMD (for its output) was the 1400 T-bird. The subsequent chips (Athlon, Barton, etc.) run cooler for the amount of work they do. For example, the 1400mhz T-bird puts out about 73.5W of heat, whereas a Barton 2500 (1853mhz) puts out around 68W of heat. If you don't have a case yet, I highly recommend the Antec SLK3700AMB. It's rather expensive (at $63 + $15 S/H at newegg.com), but you're getting an excellent case and power supply for the money. The case utilizes two 120mm fans (1xfront, 1xrear). The 120mm fans are nice because they offer optimum cooling output relative to their noise output. I have this case and it is quite quiet w/ two low-speed 120mm fans running. Remember that many other components are generating heat inside your case. Various drives, graphics processor, PSU, northbridge, southbridge, etc. are all putting out heat. Heat around hard drives is critical because it can shorten the life of the drive. The case mentioned above lets you mount the hard drives directly behind the 120mm fan for optimum cooling. |

IOW, more work = more heat, both chips have similar efficiency. Actually, heat has more to do with die/trace size, materials, etc.. than to do with the amount of "work" done by the CPU. Well, yeah, but when you're comparing similar chips, those variables are insignificant in light of work being done per clock cycle. |

Well, yeah, but when you're comparing similar chips, those variables are insignificant in light of work being done per clock cycle. While the heat is caused by the work, the materials are not the same between the AMD and Intel chips, so you can't compare them to each other. Size of die does make a difference, more than the amount of work being done. Yes, which is why the Barton 1.8Ghz puts out around 68W heat vs. 73.5W for the (larger die) Tbird 1.4Ghz, as I mentioned in my original post. I don't believe the materials between the two chips are all that different wrt thermal properties. If they were, don't you think AMD would be using those to keep their chips cooler? It's like asking why car manufacturers don't use 'tornadoes' and other cheap MPG increasers to improve their fuel economy in a cutthroat market.... answer: those cheap MPG increasers DON'T work! |
