I have a really small Acer aspire x1700 PC ![[image loading]](http://www.techtoy.de/uploads/2008/10/acer-aspire-x1700-offen.jpg)
some of the specs are:
Operating system: W7 64-Bit Home Premium
Processor: Intel Core2 Quad Q8300 @ 2.50GHz
Ram: 4 GB
Graphics Card: ATI Radeon HD 4600 series with 1GB
My problem is that the CPU and the GPU gets really hot in the tiny case.
Looking at GPU-Z the GPU goes to 100° when playign COD:MW2 and 75-80 when playing SC:2.
Because of that I opened the case, this worked for a few weeks, but now the fans get dusty and it overheats again.
Can I just buy a bigger case with more ventholes? Will all my components fit? This PC is 2 years old, should I get a completely new one?

Yes you can just get a new case. I would recommend an antec case. Great quality, great cooling. Cant go wrong. The hardest part of assembling the new case will be plugging in the cables from the case into the motherboard, You would require the manual for your motherboard to do this, or know the model and look it up online. Alternatively you might want to try going into your ATI drivers and manually setting the fan speed, I know that the early Radeon 4000 series cards had a problem with the "auto" fan control, with the fan only running at 10%. This fan control should be located in the ATI overdrive section and may fix your heat problems without having to resort to a case with adequate cooling.Thirdly, you could always try replacing (pr cleaning off excess) thermal paste between the gpu core and heatsink although this is a little more advanced and may not work as intended.

This seems to be the problem but I can't fix it, its all grayed out ![[image loading]](http://i.imgur.com/og5vd.png)

Click the key and unlock it. It's locked so less educated individuals do not mass overclock their card and encounter driver failures due to lack of power to run the clocks. Disable ATI overdrive while you are there, If you want to do overclocking use ATI tray tools.

Yeah, it works, never heard my graphics card so loud ^^. Which is the optimal speed to set it at? 100% sounds like overkill.
I'm gonna test this a bit too, if I'm still having some problems I'm gonna get a new case

Should be fine if you just open up one of the side doors and maybe another fan tbh.. Don't really need the sidedoors unless you're on a LAN or something.
|
I find 60% with my 4850 on my secondary PC adequate and quite quiet in comparison to 70%.
Rayte, OP said he opened the side of the case already. And the case he linked does not seem to have any extra fan mounts.

Actually I am on LAN cause the Internet of the house is running of a LAN switch in my room and if I'm opening another door it will get so dusty under my table
EDIT: Testing now with diffrent fan settings

By Lan, he means at a lan party despite his wording, where individuals could have easy access to your case and for exmaple steal your video card. Not being on a local area network at your own home as that has zero relevance to having the side of your case open

I had this same problem for months, I have a Nvidia GTX 285 2GB card.. I initially found a new program to regulate my fan speed, its called MSI Afterburner, you can set threshholds so that the fan speed increases and decreases with the rise and fall of your GPU tempurature. Although this worked not bad for a while, I still had overheating issues.. I also like yourself resorted to having my case open to deal with the tempurature.. Eventually I decided to take the card apart in an attempt to put a new heat sync on it, apon taking it appart, I realized that one side of my heat sync on my stock GPU was completely clogged with dust, and i was unable to notice this untill i took it apart, So i cleaned the heatsync, and the fans the best i could, cleaned and replaced the thermal paste, And i also started running On low graphics to get zero lag so i could micro better in big battles, now my GPU temp never exceeds 65C. So, verdict, i suggest getting MSI Afterburner set threshholds so your GPU fan automatically adjusts, and potentially remove and clean your heat sync, if you had your side panel off for as long as i did there is a possibility its completely full of dust.

I will be checking MSI Afterburner out, but about the heatink, there is none. The graphic card is just on top of the PC (the highest part of it) and on top if it is the fan, maybe the top of the casing should act as a heatsink? Here's a pictue take with my crappy blurry webcam ![[image loading]](http://i.imgur.com/eXDF9.png)

just leave the side panel of the case open until you can get a new one.
|
Every graphics card has a heatsink. Just beacuse the PCB is not covered by by the shroud does not mean there is no heatsink. If you take apart the shroud, you're going to see a copper heatsink with a fan next to it.

Open case is actually not a good idea unless you have a large fan to blow inside. Computer cases have a tight pattern of air flow, its supposed to come in the front vents and blow out the back. If you open the case, the flow direction changes because it is not sealed and your internal fans are not as effective at cooling as they should be.
Checking thermal paste is a good idea, its between your heat sync and CPU/GPU. if there is wet grey goo, you're good. if there is dry grey flakes, thats a BIG PROBLEM and you need to reapply the paste.
I actually still overheat playing SC2, it kills my ladder rating, it really sucks. But with proper airflow and good cleaning of the case you can reduce it.

If you posters had read the op's first post, he said he opened the case already and was still having temperature issues after a period of time due to dust.

I'm going to do some stresstests tommorow, my birthday is soon and I'm just going to get a new Case and maybe a graphics card. the heat flow point is valid, but I didn't have problems before the dust came and I have it open for 5-6 months now.
I don't know if I'm capable of taking my graphic card apart , I'm more of a software guy.
Thanks for all the help, gonna look for a good case tommorow

If you have the power available it's not too hard to add fans into a case. There are a lot of great tutorials and if you already have a hole-saw it'll be real cheap too
