Anandtech Socket A heatsink review

Hello, I haven't been checking the forums in the last days, but that does NOT mean that I've lost interest. I take your criticism very serious, and I see that you guys are obviously waiting for some kind of statement from me. I will be looking at different testing methodologies in the next...

Anandtech Socket A heatsink review

Hi, I said the 'under socket thermistor' would give similar (relative) results as an external probe, I never said anything about internal sensors (except that they're inaccurate). 47°C isn't that far away from "the 50s". If I had used another CPU, e.g. oc to 1GHz with 1.95V, then I'm...

Hi, you can't compare the values obtained with an internal probe to those obtained with an external probe (may it be located in direct contact to the CPU core, or may it be the onboard thermistor). With Athlon CPUs, there is no internal probe - so what do you want me to do, contact AMD so that...

Anandtech Socket A heatsink review

Hi, it's true that it's not possible to know the exact power dissipation of the CPU when running "just any" app, but that doesn't matter - as long as the same app is running during all heatsink tests (and that's what I did), the power dissipation is constant during the entire test...

Hi, @Mike: The power specification of 55W is only reached when "worst-case" instructions are being executed. "Full load" (e.g. when running seti@home) doesn't mean the CPU is dissipating the maximum amount of power. I used seti@home because it's widely available to anybody...

Hi, I have another comment for DaddyG: We do have the test equipment, but we use it only where it really makes sense. For Socket CPU coolers, there's no real alternative to using a real CPU and motherboard for testing. It is true that with a CPU "simulator" more accurate measurements...

Hi, @Yucky: one of the manufacturers of these infrared thermometers (I don't remember if it was RayTek or another mfr) has contacted me about these IR thermometers a while ago, and I discussed with them whether these would be suitable for measuring CPU temperature. We came to the conclusion...

Anandtech Socket A heatsink review

Hi, I am aware about the characteristics of a Flip Chip CPU. Still, I have compared the temperature readings of the KT7's BIOS to temperature measurements taken from a Thermistor in direct contact to the CPU die, and I can only repeat that the relative temperature differences measured are the...

Hi! Let me comment about the points mentioned: - Choice of the onboard sensor I did do quite a lot of experimenting before chosing to use the onboard sensor for this test. E.g. I used a thin NTC installed in direct contact to the CPU core (just like in the Slot A Athlon comparison many months...
