Parhelia gets too hot

[UtwigMU]

Get at least tall enough case that the PSU is above MoBo (Midi-Full Tower) I recommend Chieftec/Antec SX1030.

Add back exhaust fan (using zalman silent 80mm myself, get panaflo if you can) and front intake fan. You may want to add a side fan where the PCI/AGP cards are.

My CPU went down ~10°C when idle just for adding exhaust fan.

What PSU are you using? Is it brandname or noname?

strange that the memory gets so hot when it is underclocked.

[CaineTanathos]

because no heatsinks are used

[K6-III]

Yeah, but this is BGA memory, which shouldn't get hot anyway....the BGA on my Radeon 8500 128mb ran very cool, even when overclocked to 310mhz (620mhz DDR).

[Wombat]

So what if it's BGA memory? That doesn't matter here.

[K6-III]

BGA memory runs cooler because it has more surface area to dissapate heat (both above and below)

No matter with my card, seeing as it is modded with Tweakmonster tin-coated Copper Ramsinks and a low profile Vantec copper 60mm heatsink on the core. Came modded this way in trade for my Radeon 8500...

I think your missing the entire point K6-III. Regardless of what speed speed you Radeons mem is clocked at it isn't being fed nearly as much data as Parhelia's, hense the difference in heat generated.

[Wombat]

Besides that people are switching to BGA because it provides more speed and <I>smaller</I> packaging.

But can anyone really tell why the memory runs so hot, even if it's under-spec'ed? Are there memory chips that run hotter or cooler than others at the same speed and are spec'ed for the same speed? Do latency etc. timings have anything to do with it?

Ask yourself this, what is normal and how does that pertain to the heat product?

I could answer thhis quite easily, but it's time for you guys to look up that answer for yourself ie read the technical white papers to find the answer,

[Wombat]

And while you're at it, read a little more so I don't have to drudge through the "why does the 9700 have more resistors and a faster clock" crap again. THX.

[az]

Hey, hey, calm down

This was not meant as bashing the P or your technical abilities, it's just that I don't understand how similarly (I guess, haven't looked it up myself, but the threads here seem to imply it) spec'ed memory chips can run hot on one product, yet cool on another. I always thought of RAM running pretty cool anyways, actually.

[Greebe]

AZ it's just that the same people constantly ask for answers and invariably it's always the same people that answer them. When I have a question, I normally don't ask, I go find out for myself. That way I avoid mistruths, confuzzion or bias one way or another

[Wombat]

It's not even that people keep asking questions that bothers me. I encourage curiousity. Learning is cool. What bothers me is that I know that people read the answers that I write, and then ignore them.

Person X: ATI runs faster!?!
Me: It only means...(thorough explanation)
Person Y reads it: (gee, that's a lot of reading, it's easier to bitch).
Y: ATI runs faster!?!

And <B>that</B> is what gets tiring. You can put the answer right in front of people, and they'd rather strain themselves to walk around it rather than put in the effort <I>just once</I> to better themselves and their contributions.

That, and when newbies come on to MURC with these authoritative attitudes when they have no actual knowledge to back it up.

[Greebe]

or even if they do know alot think that the rest of us are clueless noobs and or talk down to us when we counter their inability to see the forest from the trees.
