Hi, I've been overclocking my visiontek 6850 and have some questions:

1.As a general rule of thumb, would I be correct to say "As long as your hardware has the right voltage, and is running cool and stable, then you are NOT damaging your hardware in any way?" Obviously the higher you overclock the more power you need, and the hotter it's going to get.... BUT if you can disperse the heat... does that mean it's fine for it?

2.If I am trying to cool my graphics card, how do I go about purchasing something to fit the fan socket on the card... does it matter that the card is a VISIONTEK, or will all 6850's be the same?

3.Are there any liquid cooling devices that will cool both my cpu AND gpu?

Thanks and sorry I know I'm asking allot of questions, but I couldn't find them anywhere... I didn't really know how to ask them in google... :/

If you can keep it from exceeding the Manufacturer's recommended temperature levels then you should be fine, Keep in mind you may be required to re-apply more thermal paste and dust out the system alot more often then you normally would.

I don't know of any liquid cooling for video cards, or any that will do both for that matter.

Last time i checked it just has to say what video card's it supports..................

But i can't give you a straight answer on that sry :( GOOGLE MAN, You will find ur answer on #2 their lol.

Thanks, I just emailed visiontek support, and they say that the card will shutdown at 116 celcius and that they consider it normal as long as it's under 100

I was kinda surprised as I can overclock my stock 775 core to 1000 mhz and only hit 82 MAX in furmark, but hey, visiontek is an AWESOME graphics company.

Upon further investigation I'm thinking I'll probably stick with fan cooling for now, I don't really need liquid cooling anyway...

Question for you pros at overclocking...

My stock specs for the card are as follows

775 mhz core

1000 mhz memory

~1125 Volt current (set in sapphire trixx) obviously not actually 1125 volts... maybe 11.25?...

Anyway, if I'm setting it up at:

1000 mhz core

1000 mhz memory

2275 Volt current

And it's run stable for 15 minutes in sapphire trixx with max temp of 82...

Is it fine?...

The simple answer to your first question is as long as the card stays cool, and the right power, and its Clean power, you should be fine. Most vid card makers are taking into account the fact that a lot of people try to overclock their chips, and are building those types of failsafes in mind in the design phase. A few years ago I would of made the argument that your reducing the life of card quicker, and while that still might be the case in some aspects of overclocking, most companies have adjusted their to designs to compensate.

There are multiple VGA Water blocks that will probably work with a 6850. Most of them are universal if you get the right series (68XX series) water block. The cpu water block just needs to support your cpu mounting type. You can run a water cooled system with both cpu and gpu connected in a continuous loop without much issue, however do your homework and see if any one particular brand fits your use, as you can buy a full kit, or you can piece one together. For example, the radiator you would need wouldn't have to be high end if your just doing the cpu and gpu, however the pump needs to be up to par, and needs to have a good reliability factor. Trust me, if you leave your rig on 24/7 like I do, theirs nothing worse then waking up to a black screen because your pump shot craps overnight. Also take into account that some water pumps out there are MUCH quieter than others. So once again, do your research. Here's a few links to reputable sights with review on water cooling blocks/pumps/lines, etc.
