GPUs tend to run quite hot, but I would still suggest some cooling solutions for your graphics cards

[Daveskater]

Josh is right, GPU's run hotter than CPU's. I'd expect mine is just under 50C right now hardly doing anything. If you don't have anything already, have some fans at the front and back of your case to get some good airflow going through, but make sure the fan(s) at he back have a CFU rating the same as/higher than the ones at the front. It does make a big difference, as I found out after putting my 120mm fan to the back.

If you can put two 80mm fans (or maybe 120mm if you have two drives) at the front of your case in front of your hard drive, then I would recommend it, as it cools your hard drive down and gets air going through your case

[Albert Lionheart]

Advice taken - but not actually done yet!

[Joshuashawharvey]

I would reccomend this cooler. You can place it right next to your graphics cards. I have read reviews on it, and it seems to be good http://www.overclockers.co.uk/showpr...=57&subcat=399

[Albert Lionheart]

thats a neat solution - however, the two cards both have gpu fans on them and they are both running. Perhaps the things are supposed to run this hot? The system is stable and the mb cool enough to show the overall temp in the box is OK. Or is it?

[Joshuashawharvey]

Well, they may run stable, but there is no harm in attempting to decrease the temperatures. The fan I suggested works well with 2 8800's in SLI, now I bet that's hot lol. Decreasing the temperatures of your graphics cards could even decrease the overall temperature of your case, therefore benefitting not just your graphics cards, but your whole system.

[Albert Lionheart]

You're right Joshua - I will deal with this when I get a moment. I used Everest to read these values - someone in 'the other place' suggested there was something better but I cannot recall what it was. Any ideas?

[Joshuashawharvey]

Well thats the only one I can suggest without taking up the entirity of your cases PCI slots, which is probably one of the main reason I suggested it. I will have a look around for you mate.

[Albert Lionheart]

Sorry Joshua - I meant the software which you can download from places like majorgeeks.com and which gives you all sorts of useful stuff about the PC's performance and so on. It is reported to be no longer supported by Lavasoft (?) hence the idea that there is something better about the net to download.

[Joshuashawharvey]

Well if it's temperatures and voltages you are focussing on the most, I would recommend speedfan mate, from here http://www.majorgeeks.com/download337.html

[Albert Lionheart]

Interesting results - different to Everest but still showing the GPUs as hotter than the rest at 68c.
cheers

[Joshuashawharvey]

Well, as you probably know, no program is perfectly accurate, and all use different calculations to determine temperatures and voltages. Yes I would definitely consider cooling for them, even though GPUs do run at high temperatures

[Albert Lionheart]

Thanks for your input on this - I have now just cracked the side of the case open to see what happens: GPU temps going up slowly; the rest no change. After 15 mins the GPU temps have settled at 74c so I am going to shut the box again!

18:25 - down to 71c

[Joshuashawharvey]

Thats a little strange. In most cases the GPU temperatures would decrease if the side panel is removed due to a larger amount of airflow. That is bad mate. Personally I would recommend having your GPUs running in the 50's idle at the most, I don't know about anyone else. As GPUs already run hot, 50 degrees will have them running at a good temperature, whilst giving your GPUs some leeway for when they are at full load. Do you have any cables around the graphics cards that could be blocking their airflow? Have you cleaned out your case of dust lately? Do you have the PCI blanking plates on? All of these could possibly add a few degrees to your GPU temperatures

[Albert Lionheart]

Joshua - you have me worried about this now. The chassis fan has a variable speed control on it currently set to min - I'll wind it up to increase the flow through the chassis and see what happens. Currently at 66c but the room is cool and the machine has only been on for 30 mins.
More anon.

[Joshuashawharvey]

Well you do have quite high temperatures mate, and and you have to remember we are in the winter. In summer the temperatures will increase even more, and then you may experience artifacts or graphics card faults. I know you are running in SLI, and it will obviously be warmer than just the one graphics card, as the cards are close to eachother. I suppose in the 60's is satisfactory temperatures considering you're running in SLI, but try and get it in the very low 60s mate

[Albert Lionheart]

Hi Joshua - I set the fan speed at max (very noisy now) but the temp has settled at 60/61c which is better. I will keep an eye on it and maybe slow it down a little to see if the temp stays low with less noise. It used to be quiet in here!

[Joshuashawharvey]

Well thats much better mate. Well as we all know, cooler temperatures come as a consequence of higher noise levels, unless you invest in water cooling.

[Daveskater]

I have found my temps to increase sometimes when taking the side of my case off. My theory is because it ruins the ATX airflow current if they're the right words. I think there used to be a picture on wikipedia to show how it's meant to go but it's not there any more.

Basically ATX revolves around air coming in at the front of your case and the bottom and going out via the PSU, with the air stream going over the CPU in the process, as I'm sure most people should know. However some people think this is kind of outdated so they brought in BTX, but it didn't get used much. If memory serves it was used on a few Dell PC's but then they gave up on it.

Albert, if you can get a 120mm fan in the back of your PC, try one of these. I think it's the same as mine and it's very quiet. I expect there are non-LED versions too if you don't want your room to be lit up bright blue
