i have a good temp fix for 8800 searies

[curt]

i just bought a 8800gts an its a damn nice card

but i cracked up soon as i saw the 63c idel temp with 74c loads no errors just hot

so i get to looking at the stock cooler an notised some [wise guy] made the heat sink so it dosent evin tuch the gpu core at all with out past

note the rest of the components [ram/power/an that video chip] seamed to be tuching the heat sink as they should [only the core had the gap]

so im like wtf how stuped is that so i cut a slim pice of copper i had under a mm thick bout the size of the core slaped it on the core with as5 on both sides

[the gap looked the be aboout a mm be twean the gpu core an where the copper tuch spot is on the heat sink]

an the thin pice i used was thin enuf not to compermise other cooling such as ram an power chips

cus if the shim/sliver of copper is to big the hole heat sink would sit to high

core temps ar nor 47c idel [still stock cooler fan at full] load 58c [thats more like it]

much happier with temps will be changin fans to soon so if it will go lower

if ppl want i can take picks of what i did an the pice of copper i cut

[francis511]

What make of gts was it . My temps are pretty high.Maybe I should take a look.

as for your fix, i would have to say that that's a nice find. most people wouldn't think to look at something so simple.

mines a xfx its the 8800gts 640mb xxx vershion

damn idel temps now core 44c load 53 room temp went down room temp [now 21c]

ambient is 29c at idel

What is it with people flipping out over GPU temps? You'd think in the midst of researching which product to buy, that they'd somewhere, somehow come across comments about temperature expectations, as nearly all GPU reviews make some mention of it these days.
Or are they just not even researching the hardware before acquiring it?


Either way, I have yet to grasp what the question here is, if there even is one?


Curt, are you worried about your temps, because while I don't belive you're running 53c under load even with your ghetto rig experiment, even 70c would be fine. It's not OPTIMAL, but it's fine.


NVIDIA should start slapping a big ass label on the 8800 boxes that says "WARNING: THESE CARDS RUN UPWARDS OF 75C; DO NOT BE ALARMED THIS IS NORMAL!"

Can you imagine how much less customer support they'd have to deal with, and how much less inane forum threads we'd have to deal with?


Hmm, that's a damn good idea. I'm going over to Nvidia customer support right now to make that suggestion.

[curt]

oveusly you have never seen a cpu that has bin running 65-80c for 6 months cus the cpu fan was clogged with dust

i dont give a crap if 75 or 90c is normal

its to high for me an the cooler it is the higher it will oc

omg get over your self an stop bashin ppl im just trying to share advice

an just so u know im not makin it up i put a screen shot up

not bad for the stock cooler

[francis511]

XFX !!?? Curioser and curioser.AND SO IS MINE.That`s it,I`m definitely taking a look.

Thats a good find curt..........don't get caught up with the 2 negative posters here...they must not have had anything better to do than to bash what seems to be a nice fix for high temps on the 8800......hmmm...just like you posted.

Once again....good find. :toast:

[curt]

still playing with my 8800gts an as i was saying i fixed the temp prob so i thout id try more

now in the video pic u can see a big 24volt fan i just mounted for testing [ran 58c load temp with my shim an stock fan]

an the pice of copper is what i used to make the shim i had 2 of thows pices so i took the flatest one an cut a nice shim give u an idea how thick the gap was

with the [stock fan an fan case on] @ 100% an room temp of 21c video idels 45-48c

ok lol big fan on video isint evin spinning yeat an im holding 52c idel stock fan is going but no cover to guide the air [stock fan will be put to 25% for big fan test]

stock fan at 25%

big fan at 10.66volts idel card temp 50c
----------17.26v idel card temp 47c
----------18.73v idel card temp 45c
----------20.50v idel card temp 44c
----------22.20v idel card temp 44c
----------27.10v idel card temp 43c

testing 18v on big fan stock @ 100% 44c idel

so im just guna run the stock cooler my big fan dident help much

just thout id try dont get me rong im quite happy going from a stock card idel of 63c down to 47 with just a shim or thin slab of copper

first pic of video test fan an [copper fin i made shim out ov] the other 2 ar my comp an cooling since i havent put any up in a wile [yes that is a a/c unit in a water tub] an the hot air from that gets pumped out side via

a 1/4hp heated air fan on a dimmer cus the fan is vary loud [an suckes enuf air to make it hard to close my door] if that fan is going full u cannot swing my door closed too much air flow u gota actuly push it shut

CPUs and GPUs have hugely different thermal thresholds. GPUs will work up to 100'C (not long term of course) and CPUs will work to 75-85'C.

So 74'C on a GPU is NOT bad under load. I'd be quite happy to have that temp under full load, especially on such a hot running card as that.

And yes, I've seen a CPU running at 90'C (my bro's old Athlon XP) for well over a year, it was nicely blackened (still worked surprisingly lol).

And before you say anything, I am NOT bashing your work, I think it's very very interesting that an extra bit of copper decreased temps, I would have thought it was the other way around (more space for the heat to pass through). I'm just merely stating that (while harsh) newconroer was right about the temps being high :)

[curt]

i aim for under 50c on any divice i dont care what its rated for cooler parts oc better 90% of the time

allso i dont feel like looking at a crispy video card one day when i planed on lan gamen

an arnt dule core t max 49c? where do u get 75c

i found it mostly dipends on core speed for instance

my xp3000+ could do 120c temp meter stops at 120c at 1.6gh stable playing a game i melted a fan an brouned my socket trying that but it worked

now the same cpu at 2768mh would crash at 25c
but was stable under that hard to keep under 25c thow

the resons i worry about heat so much is for the board an pcb sake mostly the cores can take unbeleavable like white hot an not break but the pcb is much more vulnerable as it does has some mosture in it as some of u may have seen bleeding pcb.s an some times evin bleeding [ram just the plastic around the core of the ram] if seen many times where something burns as in the case of welder vs video cards chips can leave a wet residue evin older dryed out ones if they get to hot/dry they crumble

[like a ram chip cook it with a blow torch till its done burning an it will crumble leaving the ram core intact] [some ram cores look wicked under a micro scope] :) like a bga one i did so cool

my point is just cus the core can take 100c dosent mean it should be or that the reast of the components can take it

mind u it does take years but still [lower temps higher oc]/more stability

[Morgoth]

now the same cpu at 2768mh would crash at 25c
but was stable under that hard to keep under 25c thow

i have no problems with my cpu running at 25c

You should have called it: How to make a 8800 look like crap.:laugh:
Come on man are you really that obsessed with heat that you demolish your card for it.:twitch:

[Wile E]

an arnt dule core t max 49c?Absolutely not. My 6000+ on stock speeds with he stock cooler is warmer than that. But it's not 75C for all dual cores either. The max for AMD ranges between 63C and 75C, depending on the cpu.


But, anyway. Good work on finding the quick fix. I guess tolerances aren't too tight for the stock coolers.

[Richieb0y]

LOL if i set my fan of the VGA on 100% i get those temp idle and load and on 60% i get 50idle and 65 load.

and a ohter thing a friend of my got the same card as u only 320mb and he get those temps
theres noting wrong whit those temp he even mailed xfx for the temps and they siad 85c is bad.

my card is a A3 rev

[largon]

Come on man are you really that obsessed with heat that you demolish your card for it.WTF does it matter what a VGA looks like? It's a computer part for crying out loud...

curt , Good job on fixing heat issue! I refuse to let my GPU go above 68c and run the gpu fans at 100% always for gaming and 58% for non-gaming..!!!1
Now for me the main abjective is high clocks with low temps and what ever means is possible..IF it looks like frankenstein then so be it..
I am always trying to figure a way to cool it more and clock it higher..lol..! Again Sir great fix and great job at cooling for minimal cost!!!:toast:

[rangerone766]

dell laptops also had the same problem. my 8600 with a radeon 9600 pro turbo would lock up in games at stock speeds. after i modded it with the copper shim i could oc the hell out of it.

i miss that laptop it had a pm 2.0 in it and it was fast. i traded it off tho.

let me find my pcmark score for it. btw it was overclockable to 2.4ghz

Well to add on to the excitement here, i have found a temporary fix for single slot coolers, (not a temp fix for me).
I saw my gpu temps really high topping at 95. so what i did was get a spot cooler and take out 2 slot tabs and blow air out them. now my temps stay within 56 to 64. thats also when i overclock. no change in temps.
I am big over temps too i cant stand see temps like that and i really don't like seeing 50's and 60's. Heat does effect performance. if you didn't already know so i think getting the temps down as far as possible it the best thing to do. hey its extend the life of your components.
and honestly who stares at there damn components 24/7 or even 5 mins at that. I'm to busy using the damn thing.

[Kursah]

I focus on Case/Component Air Flow and at least semi-decent coolers, but Curt's trick here has some very interesting results, very nice find dude! I'm planning on modding my 2 80mm intakes to have no mesh to restrict airflow, they will still have the Spider Filters, but the metal mesh will be gone and that should increase CFM somewhat, and also planning on a fan mod to direct more air at my x1950. Haven't decided if using an intake from the side window, or from the bottom of the case with a mount, aiming directly at the card...

Either way good job Curt, I do agree with others that your spelling and grammar need some work, and it would be easier to understand you, but I didn't have to read what you wrote twice to get it. Maybe that's the complaint others had! :D hehe j/k

I am a person that likes my temps where I want them, some people don't care and that's fine, but I like a cool running machine that OC's well, doesn't need water to get there, and so fourth. Makes my builds get more and more interesting, and it's a good challenge. Everyone has their own style and preferences, and noone else should oppress others with their own preference, just offer it as a suggestion or opinion in a respectable manner.
