whos idea was it to make the fans and good looking stuff on gpus facing down

whos idea was it to put the fans and good looking part of the gpu onf the bottom instead of facing up where everyone can see it

If your case allows, you could mount the GPU on its side, or get an adapter if doesn't. But you lose your rear I/O if you do.

yeah i know about that, but it would be cool if the fans and cool looking plating were on top

In some cases the motherboard is inverted, that works too.

ooh i like that might get a case that can work with that

Also, if they just flipped gpu's and left everything else the same the cpu temps would take a massive hit. Having the highest tdw component of your system blowing on to the cpu heatsink, ram, vrm, etc would not be beneficial

might have something to do with wanting air thats not coming from a hot cpu maybe?

the fans blow against the card to cool it so it would blow against the card and go out sideways

hot air rises.

yes hot air naturally rises. But not when you have multiple fans pulling it down onto the video card.

 

 

[mariushm]

fans take cold air from the bottom of the case and from the front fans (  where the drives used to sit) and push it against the heatsink and push the air through the fins of the heatsink. This action, airflow through the fins, is what transfers the heat from the fins into the surrounding air.

The air continues to be pushed all around, a large part will go left and out the case, a part will go over the video card and rise towards the cpu area etc

 

If the fans were the other way, fans would draw warm air from the cpu area, push it down on the card and the warm air would go back towards the cpu... you'd cause "turbulence"  in that area and everything would heat up

The cards are in the downwards direction because that allows the first pci-e slot to be practically near the IO shield and just close enough to still leave room for the cpu cooler.

If you had the cards in the other direction, you'd more or less lose one slot on the board because the first slot would be shifted a bit down.. also, if you have 2 slot or 2.5 slot video cards you'd basically have unusable slots covered by the video card

This, so much this.

even with a badass mesh case you still have to deal with the direction of air.

 

or do you mean the looks wouldnt matter if people didnt have side windows?

 

I mean you can buy plenty of nice cases with no window in that case.

Not an expert, but I feel like this is purposefully done in order to keep away from the warmth of the CPU as much as possible.

Intel.

 

Before PCI came along, the then slot standard was ISA, which had the cards installed with the components facing up. You can see it in this video (at around 27:00 if the time stamp thing doesn't work)

 

But when it came time to roll out PCI, which was invented by Intel, they had a concern: how do you split the number of slots between ISA and PCI? Rather than make the motherboard manufacturers choose how to allocate 7 slots, Intel decided to make the PCI cards install upside down. This allows a slot to fit either an ISA or PCI card. Like in this motherboard:

Although in practice, I don't know how many motherboard manufacturers actually put in more than one slot where it could fit an ISA or PCI card. After that, it was just convention.

thankyou for giving me the answer i was looking for!

thankyou lol

A case with a glass side panel is not a problem. It's when the entire thing is surrounded by glass it gets to be a little overbearing.

Mira Yurizaki has the right answer.  But there's more to it than that.

 

When PCI was being designed in 1990-1992, there were no expansion cards that generated enough heat to require a fan.  Not that it mattered anyways.... the direction the card faced was irrelevant, because horizontally-oriented "desktop" computers (the ones which you'd put your monitor on top of) were still the dominant form factor.   The narrower "pizza box" style cases, like the PS/2 or some Macs, would turn the expansion cards sideways, but it still didn't matter since these things didn't generate much heat.

 

All of this was powered by a power supply that provided maybe 200 watts, tops, and more often than not, the PSU was the only thing in the computer with a fan.

 

Also.... the "Mid-tower" case style we all know today was almost never seen outside of network servers and high-end workstations before 1992.  Apple's first mini-tower machine, the Quadra 700, started at almot $11,000 USD in today's numbers.  Dell's tower machines were $15,000+.

 

Computers of the time also typically had 3 - 5 cards in them.  The "Baby AT" motherboard layout only had a single PS/2 plug on it for a keyboard.  If you wanted to connect a mouse, modem, printer, joystick, drawing tablet, audio, floppy drive, network, tape backup, hard drive, CD-ROM..... everything required expansion cards.  Machines could get packed pretty tightly.... but airflow still wasn't much of a thing.

 

Here's a typical motherboard from 1993, with an AMD 486 DX2 chip on it.  No heatsink required.... no fans.  Just a completely different world than what we're used to now.

thankyou for adding on, im generally "young" (born in second half of the 90's) and dont know alot of the history of tech.
