Still think G-Skill knocked it out of the park with the Trident Z. This kind of feels like a weird off-brand version.
But, as someone tired of "black", I'm all for more white/silver components. Black components remind me of 2006 to 2009 vibe: "everything black and a blue CCFL tube".
That's some very poor and shortsighted engineering right there. The two inner modules have almost no area to dissipate heat and are sandwiched between the outer modules, receiving their heat too. No gaps between the modules means no convection and no cooling.
What do you expect? They grew up with flashing colored lights on their sneakers!
I walked by the Skechers store in the mall last week. ALL the shoes in front of the store had blinking lights on them - not just a few of them as I would have expected (perhaps a young manager?). It made the classy ads with Joe Montana simply stating ‘I was a football player’ seem like a distant memory. Needless to say I didn’t go in.
Conduction The word you were looking for was conduction. And conduction happens so long as there is a fluid medium with which to exchange phonons of heat energy, while convection requires movement of said fluid medium, greatly increasing heat dissipation. Conduction is ALWAYS happening so long as there is a temperature difference (and you aren't in a vacuum).
Yep, that's why contrary to some sci-fi, you don't immediately freeze up in space even thou it is ultra cold. There is no atmosphere to conduct heat away from you, absent any fluid medium you can only lose heat by infrared emission.
Convection will also occur if there is airflow, but its mechanics will be disturbed by it. If there is gas, it will heat, thus its density will drop and it will rise, causing negative pressure, which will suck in colder and denser gas. Convection causes airflow too, just in a different manner a fan does.
Ram modules are usually oriented in such a way that they'd be perpendicular to the airflow, I mean the flow that goes through the CPU radiator and out the case rear. In this aspect, case fans aren't really doing much good as the orientation results in dead spots, which is where convection kicks in, ram sticks usually being vertical, they'd suck cold air in the gaps between them from the bottom and push it up.
Cases with fans on the top are a tad better, as they will create some airflow that is parallel to the ram modules and could get in the gaps between them. But many cases do not have those.
Of course, the lack of gaps between the modules doesn't help fan-made airflow neither.
That is supposedly how multiple 400 watt blower type Nvidia cards get cooled. By case fans that sound like jet engines, that is. I am skeptical of that explanation but that is how it is generally explained.
I applaud Corsair for being willing to release these. Not because I'm a fan of white (meh) or RGB (cancer); but because by designing "heat sinks" that seal off the center two dimms from any airflow or ability to radiate heat from the sides they've demonstrated how utterly useless they are.
It actually might have taken a lot more engineering than apparent. However, they did not put it into making the product durable and reliable, but by carefully engineering it to under-perform thermally on purpose, timed to cut the product lifetime to a desired period, usually just after the warranty period expires. You promote extra sales this way.
Those modules in particular will most likely cool better without the heatspreaders. A ram stick is big enough to displace even 10 watts on its own, but when you suffocate it like that, cooling performance will likely deteriorate.
yeah, because RAM gets so insanely hot, right? You are looking at +15~25c over room temp at full load. Hardly the kind of temperatures that will quickly burn out chips.
How hot it gets depends on how much heat it generates and how much heat it is able to displace. Even a little generated heat will gradually build up and become a problem with instead of cooling you have an insulating solution that also adds additional heat.
I had 64 systems in my farm, about half of them had 4x4gb ram, the rest 2x8gb ram, and it wasn't anything high end either, it was low profile ddr3 1600 from corsair with a basic heatspreader, running at stock volts. In 5 years I had only a single 8gb module fail, while the whooping 12 4 gb modules failed in the same amount of time.
That to me is clear and obvious evidence that heat matters for product durability, the systems with 4 modules had the modules significantly warmer than the systems with 2 modules, having the modules spread further apart improved temperatures by about 15 degree C.
And even the systems with 4 modules had some space between the modules for air to circulate, whereas the modules from the article are literally packed together like sardines. Even thou voltage is slightly lower for ddr4, they are higher capacity and higher clocks, so I doubt they will run sufficiently cool to not be at a detriment from that moronic design.
I think they've finally proven it, there are two types of PC builders. Ones who want their computer to look like a Christmas tree and ones who don't care what their computer looks like.
I'd take the least expensive and least environment-impacting solution, which involves no coloring whatsoever. The natural color of PCB resins is usually in the range of brown-yellowish through brown to brown-greenish.

by the way.convection only happens when there is no airflow.
when you have a case fan convection does nothing.
it´s a thing often missunderstood by people with no background in physics.

RAM doesn't get hot, the heatspreader is just there for looks. Heatspreaders don't do much unless they're attached to a heatsink anyway.DanNeely - Saturday, September 30, 2017 - link

Well, I looked it up, and each DDR4 DIMM consumes around 4Watts per DIMM, 6Watts if the voltages are really pushed.Even 6W per DIMM is hardly going to require any cooling at all.
