The actual number of CPUs sold must be way lower than Ryzen 7 2700(X).

... this is in stark to a fan, which typically has a range where the effect is gradually rising / decreasing with the fan RPM. With a pump, there is a wide range where cooling is almost constant...

The impellers are free floating within the housing, but I guess you mean the housing isn't decoupled from the rest of the surrounding?

Motherboards with B450 are more cost effective unless you need the extra bells and whistles of an X470. As for RAM it's your motherboard that dictate what specific models work best. You should opt for (at least) 2x8 GB rated for around 3,000 MHz (or more). With a high memory frequency the latencies ...

It's hard to determine what's the original problem here. If the resonant controller died first it's possible the switches got into an "always on" state, resulting in a sudden very high output voltage. The OVP may then not have had time, or even been unable to, react. (Unable if it relies on the reso...

So, are there two kinds of pumps: piston and waterfan based - used in PC water cooling? No, only centrifugal pumps are used here. Reducing the pump speed can be a viable option, but how far down you can/should go depends on your flow rate . The youtuber JayzTwocents claim that " Pump speed doesn't ...

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...

That's the problem, it's a Pump. PISTON, it pulls and pushes, pulls and pushes (want me to say it again) You don't need a Pump, you need a Circulator. In place of a Piston, a Circulator will have an Impeller (water fan). You really don't know this, do you? There are several types of pumps, and ever...

I find it unlikely that AMD will kill its own Threadripper line up with the R9, and the 135W seems way too good to be true. The Threadripper line won't be killed by the suggested R9, since Threadripper will also be updated. Expect up to 32 cores initially and possibly 64 cores later on. 135W TDP al...

If anything I'd now recommend not a Core i5. Reason being that over the past year more games are optimized for eight threads and don't run very well with less. The options then stand between any Core i7 vs Ryzen 5/7. (Forget about the Core i9, it's too power hungry!) If you primarily want a high per...

AC electricity is first filtered (with or without active or passive PFC). Then converted to DC voltages. The 3rd time. Was this sentence correct? Just look at any decent PSU review: The first thing at the inlet is a ferrite coil or similar filter. Then, as stated, the AC is rectified before being c...

A surge is electricity. It must have an incoming and a completely different outgoing path. If incoming was on a TV cable, then what was the outgoing path? The cable consist of two wires (coaxial) that typically only has a low voltage between them. When there's a lightning strike into the ground nea...

Just wanted to chip in that the one time I've had a surge problem it came through the network cable. (Using cable-TV for Internet as well.)
The WAN-side of my router died quietly as a result.

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.

(Assuming a regular tower case, or similar, is used.) It's "difficult" (read: as good as impossible) to place an exhaust fan behind the graphics card. Exhaust fans above the graphics card will a) reduce the flow of fresh air to the volume below the graphics card (where its cooler typically need it),...

... top exhaust fans are more effective than back exhaust fans, since warmed air rises, and top fans "work with" this. While it's true that warm air rises (if left undisturbed) this effect is so small that it's negligible if there are any fans involved. The graphics card is a key area - if the case...

I agree that the shown "test" doesn't answer the given question. Not one bit! The key factor is power consumption: - For high power builds (>250W or so) an open design is better unless thy use a custom water loop with a large external passive convector for cooling. - Very low power builds (<100W) ca...

Yes, it's an interesting topic. ... in most circles TDP and power consumption are used to mean the same thing: how much power a CPU draws under load. Just to be clear, it should read: "... how much power a CPU draws in average , over a time span , while under a typical load." It's never been the pea...

Here's my opinion: more exhaust air flow is better / quieter - for two reasons. The main one is that exhaust fans are more efficient - since lowering pressure is going to shift air far away from the fan. The best illustration of this is a whole house fan - it exhausts air from the attic, and if the...

By stronger, do you mean more RPMs or larger size, or both? "Stronger" means "able to build more pressure". Traditionally "strong" fans are thicker than their weaker equivalents of same diameter, and produce more noise at the same speed. There are some better designs that are neither thick nor nois...

A reflection of mine is that the exhaust diffuser cone is pure rocket science. Not as in "difficult" but as in "how to define the proper shape and size of the end bell". On a rocket engine you want the exhaust gas pressure to be identical to that of the surrounding atmosphere at the point where it l...

Shouldn't be too difficult to find another screw with the same thread and then adjust the length.

I bet the code differs, but in practical terms there's no difference to the user.

A single fan should provide the best performance to noise ratio. Adding a second fan will more likely introduce interference noise while not adding much in terms of cooling. If your current fan is insufficient even though you have made sure: * the cooling fins are clean. * the cooler is properly sea...
