Re: Choosing surge protectors

DC is converted to AC. Not to radio waves. Let's take a rectifier, followed by a capacitor. An input spike would appear on the capacitor. Would appear on the AC. Perhaps would appear on the "rock stable" DC output. AC is not dirty. AC with a 100V spike on top of it is dirty. Might kill the switcher ...

I guess the CPU temp is wrong, but why?
1. Probably yes. PWM fans usually have some min speed. Search spcr for more info.
2. Because the manufacturer has not given all the technical information to the author of Speedfan.

Why would anybody suggest 210 ? Weaker than some integrated, with more power draw.
8600GT is a hot old card, should not be passive.
Check HD4670, GT240 (both 2x faster than 8600GT) or newer and cooler.

Re: Choosing surge protectors

You really don't know what you are talking about. Radio waves are a "type of electromagnetic radiation", waves in wires are not radio waves. 100kHz equals to a wavelength of about 3km, how would you place that inside a PSU? Pure and stable 300V 100kHz power is not dirty. Power is dirty, if it contai...

A MOV costs half a dollar. All the rest is marketing. The best bet is to buy just a MOV. Yes, your MOV may be dead after one big surge (or several not so big surges). Replacing after 3 years, whatewer, seems stupid. Just buy a bigger MOV (or connect 2 or more in parallel).The voltage at which the MO...

PWM is a good thing. 90°C is not a good thing (power draw is bigger, stable frequencies are lower, card's lifetime is less).

S1 is big. I don't think you can use it with any of those VRM coolers. I'm not sure; even if you can, the card would be a monster.
S1 comes with a VRM cooler, which fits under the S1.

The unit will get hotter, the fan will start. Don't worry. Your system does not draw 500W, any fan will do. If you wanted to take max power from the PSU, then the fan should be similar to the original (rpm, amps).

A resistor is the cheapest, but you might have to try several. Some 56Ω 0.5W. I used one recently, got a strange effect: after some time the rpm reading was a half of what it should be, and remained that after a restart. Then I put there 24Ω, was good for my needs. And the fan's switching noise, rat...

The last digit (after the decimal point) is not to be trusted. I connected a 62kΩ resistor and paralel 68nF capacitor. Got 1.2W 45% PF (should be 0.8W). Then I added paralel 217k and got less power - 1.0W 45%. Which means something is wrong in the digital domain. Perhaps one digit of the ADC is dead...
