View Full Version : Does the X1900 series get this hot?

I mean when I saw this a while back it got me thinking a whole new way of keeping this "card" (notice I didn't say GPU) cool. Take a look for yourself. Some of you may have already seen this.

120c seems crazy, but Its hard to doubt my core once read 97.9*c which is way too hot, it was with an FS-v7 cooler though which I removed, and now have back the stock cooler

Did you change pastes and lap?

I will put some sort of air on the entire card now. I need to make sure the entire card is cool. Maybe it will render 1 extra frame but I am looking at the longivity of it. I am looking to cool the enter card now...not just the GPU/Mem/Vregs/Mosfets. I gotta bad feeling about water cooling if you do not put a fan on the front and rear of this card. That explains why that other board was damaged from previous thread (http://www.xtremesystems.org/forums/showthread.php?t=90373)

If you actually read the thread you linked to before posting, you'll find out that the author realized that the temperatures he 'measured' were plain wrong.

Are you talking about using the correct emissivity (http://www.temperatureconsultant.com/EMISSIVITY.htm)
Yes, I read down some more and read that, oh well that's life...

Nevertheless, that's very interesting because he can find 'hot spots' on all the hardware :) Then we can see where heatsinks are needed.

Mine has hit 100+ before...once...I didn't let that happen again that is for sure...lol...it scared the crap out of me...

could this be why ati reduced their warranty to 1 year? Its hard to imagine a card thats hitting 95C+ lasting for more than a year.

I doubt it. It really depends on the process and design. For some chips, that's critical for others it could be normal.

Anybody want to volunteer their X1900 to see @ what temp it will crash / die? ;)

and i thought 74c on my X850XTPE max overclocked was hot... lol.

90-100c is wrong. And if you put it on water, it would probably still get into the high 40s ><, not to mention dump a ton of energy into the loop

ATI should ship a new X1900XTX "OC". The heatsink will look like a giant kettle. Every morning when you wake up, you pour some water into the container. You turn the computer on, and run a few 3DMark loops, while you dress. 10-15min later you have hot boiling water for some fresh brewed coffee.. yumm!

LOL

It should be CO instead of OC, CO for COffee :)

This is why I prefer 7900 series over X1900. Those cards put out a immensive amount of heat and that means they'r loud too with the stock cooling and consume a lot of power.

Wow, look at all the Nvidian fanboys coming into the thread to flame...is this necessary?

Just saying few fact's, nothing more. Your post looks more flaming than mine btw.

Our cards have better image quality and survive better at high AA and AF?

I dont care about the noise, and I run at 1600x1200, so ATi for me, i will never go nVidia again, my 6800U was AWFUL.

Now, I saw a thread where someone had lapped there stock HSF, will that *really* make a huge diff? As the HSF is actually pushing alot of heat allready?

My mems getting cooked by the core, I have 1.1ns and im limited to 666/1680...

weee neeeed a better air coooooler!!!

just the facts man, just the facts... (maybe perhaps a watercooled X1900XTX would be cooler/quieter than 7900GT..still more power). Also, nobody here is denying you'll get higher 3DMark2005 with X1900's. If you want the best performance you definetly have to make compromise on heat/noise.

Concorde Rules, Zalman and Artic Cooling... unless you are good with metalurgy and mechanical engineering.

Zalman 7000cu/alcu would be very powerful and quiet cooler for X1900XTX and it's not that difficult to mod to make it fit.

Well, I know about the VF-900 coming out, but I wont be modding my card just yet, I dont want a dead X1900XT, which can be flashed to XTX ;)

I have never lapped a heatsink before so will admit my ignorance on the matter. can someone give me some pointers on exactly what I need to make this happen? What grit of sand paper etc? Do I need more than 1 grit type? Do I have to use or do anythign to polish it in the end? Does it matter in what pattern I do the lapping etc? This is the kind of stuff I am unsure of. Thanks.

Start with a low grit like 1200 and work your way to say like 2000 grit sand paper is my understanding of it...BUt you have to do it at a level surface all the way across the heatsink so it is perfectly level with no lowered edges...

And yes at the end it would be nice to get some copper polish to buff the surface all nice and shine so you can see yourself in it.

Is this correct guys?

This may not help much but when dealing with a GPU HS there is actually very little sanding involved. All you really want to do is remove the drill marks from the copper HS itself. At the same time you want you HS to remain true thus lapped. Here, a link (http://forums.techpowerup.com/showthread.php?t=8385)that gives some info on this cooling your card

ok-- im gonna push the boat out here an suggest the heatsink is not the problem with the x1900 its the fan. replace the fan with somethin that can move serious air thru your heatsink body and your off. ive tried a custom 80mm with a funnel and sealent but the sealant wasnt strong enough. but the idea was sound. better still would be if you could focus the air from the other end and then out the case.

yeah, what he said.

personally I start with more readily available 800 (wet), and follow on with 1200 or 1600 (I dont have higher). Very important to use a very flat surface like mirror, or another heatsink ;)
In addition to doing a oval pattern, I periodically rotate the part being lapped. I typically do it very lightly, just enough to get rid of most of the bumps (try running across surface with needle to see if its smooth enough)
There are some people that really go overboard, as if they were sanding down a hole to center of earth or China or something :nono:

here you go this is what you want to sand off. Wet sanding is ideal.

here is how you want it to look. The camera had a hard time remaining focus from the birds eye view on the surface after the mild lap do to the reflections.

this is a very over looked simple mod I dropped my avg idle temps by almost 5c I would say just by lapping stock hs and adding AS5. I stoped at 1500grit.

If you've ever run the stock fan at 100% and felt the air coming out the back you'd know this is not true, the fan and shroud is excellent.

Its loud but it moves a ton of air.

The OEM GPU heatsink could probably benefit from the addition of some heatpipes and a little more mass in addition to the lapping done.

btw to those that lapped the heatsink do the brass pins come out?
