Why Intel Processors Draw More Power Than Expected

Interesting article on Anandtech: Why Intel Processors Draw More Power Than Expected: TDP and Turbo Explained One of the recent topics permeating through the custom PC space recently has been about power draw. Intel’s latest eight-core processors are still rated at a TDP of 95W, and yet users are se...

Re: One or Two front intake fans?

The GFX card will be an MSI 1060. So, maybe I won't need a side panel fan, but the article said it was good for cooling the chipset as well.

I think I will at least try the two rear exhaust configuration. Would two 120mm be better?

Re: One or Two front intake fans?

So it seems, in general, it's a little more effective to pump the heat out of a case than to draw cool air in. And also that article found that having a side panel fan can be very beneficial. I will first try putting one 140mm at the front, mounting a 140mm on the side panel, and putting a 120mm rea...

Re: One or Two front intake fans?

Ok, what about two 140 mm fans running slower than two 120 mm fans? I guess my questions all boil down to, what is the best configuration of front intake fans for the best balance of airflow and quietness? I have a Fractal R5. I'm still not sure whether to go with one or two fans in the front, or wh...

Not sure I follow: if the filter is so air resistive, then making the whole case out of the same resistive material would make the whole case just as resistive, no?

Re: You may not need as much wattage as you think.

So it sounds like most current systems on average, would use around 80-110 watts just idling. ... Idle system use is less than half of that, typically 25-30W, unless you overclock manually. Well, this test on the 2700X showed 68W at idle at stock. https://www.bit-tech.net/reviews/tech/cpus/amd-2nd-...

Re: You may not need as much wattage as you think.

So when looking at specs, do I add up all the 12 V rails?

For my Seasonic 550W that would be: 540W + 3.6 W = 543.6 W. Is this correct? How do I know which 12 V rail is for the CPU, GPU, etc.?

Interesting. But you wouldn't necessarily need to make the whole PC case out of HVAC filters. Why not just place HVAC filters where the case openings are?

Both come in 120mm and 140mm sizes. The HP series are 4-pin PWM fans, whereas the HF are 3-pin. They have received generally positive r...

One or Two front intake fans?

I was just wondering: is it better (i.e. quieter) to have one 140mm front intake case fan running at a higher rpm, or two 120mm fans running at lower rpm? (everything else being equal).

Hoping to see some lower TDPs in this new series.

MSI, Asus, and Zotec, would be the third parties to watch for quiet versions.

Re: Tempered Glass -- Worth It?

Yeah, I guess it depends on how the window panel is designed and attached. Also, whether it's a full glass panel or just a half window. And I think Be Quiet has a TG side panel on their 900 case that has foam/rubber around the edge.

Are those online PSU wattage calculators reliable? They keep telling me my wattage use would be around 450W.

Re: You may not need as much wattage as you think.

If people are buying a PSU not for their normal usage but for their peak usage, then they are not "buying PSU's far bigger than they need for no practical reason". They still need a PSU that will deliver power for their peak usage.

Thanks. I see what you mean. However, people don't buy a PSU for normal usage, they buy a PSU to accommodate their estimated heaviest workload needs, so that they have enough headroom for those few times when they do use a lot more power. I could see how using a much higher capacity PSU might draw m...

Re: You may not need as much wattage as you think.

I suppose compared to a 650W PSU, it would run a bit warmer with the fan coming on more often. Not necessarily. The efficiency dropoff at max load is small so the extra heat output (even if you were running at 500W+) would be only a Watt or two. With higher rated PSU's they will often up the fan ra...
