Re: Testing my understanding on case/build philosophy

One key question that hasn't been addressed is what background noise there are in the room.
It make a huge difference if you're living in a rural area and use passive ventilation in your home or if you live at a busy city street with a/c and forced ventilation.

Re: Cooling research

As I see it there are currently three major types of liquid cooling, listed below, and a new product should bring some sort of improvement to any one of these. 1. Heatpipe. Fixed format cooling where the heat is transfered a fairly short distance from hotspot to cooling fins. Cheap and efficient. 2....

Re: M.2 SSD under GPU: Bad idea (in a quiet PC)?

I think this isn't a simple yes/no question. As long as the heated air from the video card is sufficiently cool there shouldn't be any problems. For that air to be cool enough a good combo of low power video card an high fan speed. No 250+W video card rigged for quiet running will fulfil that prereq...

There's a bit of a price difference to take into account. With a Ryzen 5 3600 at the same or higher price than Ryzen 7 2700X the latter might be a better option for highly multithreaded tasks (at that price point).

Re: Should I replace the stock Define R6 fans or its a waste of money?

Start out by using what you have! Is there a problem? More exactly what is that problem? If too much fan noise, reduce the fan speed and/or adjust the fan curves. Do take all fans into consideration. By speeding up a relatively quiet fan you might be able to slow a noisier down while maintaining acc...

Re: Is WEB losing its value?

I agree with the futility in broad "hunting" for information.
What does work is to have one or a few trusted reviewers and keep an eye out on what news they present. Then, if you find something interesting, you can try to find other opinions on the same product.

I can confirm this. "Needed" is if you either have two PCIe 4 NVMe SSDs in SATA 0 and shift loads of data or if your computer case is really hot inside.

Re: Best cooling combo

Your suggested cooling solution should be fine unless there's a graphics card that also need some air.
With a graphics card the primary concern should be to make sure there's a steady flow of cool air in the lower region of the case.

If you upgrade the exhaust fan you could expect some affects: Sucking cool air away from the graphics card the GPU should run hotter and its fan run noisier. I'd suggest you first try to simply turn off the exhaust fan completely and study the overall effects. My son also has a Define C case, and th...

It's hard to determine what's the original problem here.

Re: Is there a diffrence between a dual loop or a single loo

I would definitely recommend a single loop. The reason for this is that you often will have either the GPU or the CPU running hard at the same time, and then you'll always get optimum cooling of the water with a single loop. As long as you have a decent flow rate the order of the components in the l...

More fans will generate more flow.
No general difference between positive and negative pressure, other than that of filtered vs unfiltered air.
Hot pockets should only emerge where no cooling is needed anyway.
