Need advice with water cooling - Page 3

post #21 of 23
Imo front looks a lot better and the rad or fans are not exposed so any damage can't happen to the accidentally. Some people like external rads tho rolleyes.gif
You can use universal block too they are just as good but you need passive heatsinks on the vRAM and power delivery chips and a fan blowing directly a them and if you got a rad in the front there wont be all that much air coming in. Unless the fans are >9000RMP, you would need a third fan there.
You can also have HDDs in the optical bay area with adapters.

Majority of people will say full coverage block is better than universal block. It makes sense to say that. I don't agree with it nor do I disagree with it. On a 6xx card where it makes almost no difference to increase the voltage I can not see why active water cooling on the VRM makes a difference when the original cooler didn't even cool the VRM just the little VRM heatsink that stays on the card when you remove the main cooler. But if you are going for looks as well then there is no mistaking that a full coverage block looks better. Do you already own the block? If so then that is that. If not just be very careful that you get a very low restriction block. Some have very poor flow some have great flow.

As for where the fan goes...

Regardless of what others may say you really must push cool air from outside the case into the radiator. You should not push air from inside the case through the radiator. This means that you have to get it out of your head that the top fans are exhaust fans. If you can not do that then I recommend you put the radiator in front where it is clear that the fans will be used as intake fans.

Air looses its ability to cool very quickly and your radiator waters temp will only be a few degrees above ambient. The temp in your case will always be somewhat higher than the temp outside your case and that little difference is more than enough to impact the performance of the radiator. In other words if you mount it on top just be prepared to reverse your thinking and make sure the fans are pushing cool air in.

On my case I have no exhaust fans lol... I have 4 intake fans because of the radiators... all the air being shoved into the case escapes through a vent I can feel the air coming out... it is not a big deal to have only intake fans.

I'd go for the front though for the time being... you may eventually end up with 2 radiators but for now even though it is more work I would go for the front so you can still have your exhaust fans.

edit



This is what a universal block would end up looking like. On my card you can see a heatsink to the left... that was on there from the factory. I put the heat sinks on the memory BUT!!! they are def not at all required and probably do nothing for overclocking the memory because you can't overvolt the memory. Regardless I put them on anyways.

I have a hard time believing that a full coverage block can outperform a universal block on the sole task of cooling the GPU itself... some of the block designs are very basic and use only a few channels to restrict the water and cause the cooling. Universal blocks are designed more like CPU blocks and often have intricate designs that I have a hard time believing are not the better of the 2 solutions.

I once said how I felt on a thread of people that love full coverage blocks and have tons of money to blow... the guy was saying he couldn't get a full coverage block for his 7970 and when I recommended a universal block I was completely flamed like I was some idiot... so they def believe that universal blocks are complete garbage and the only block that should exist is a full coverage one.

Unfortunately no shootouts that I could find on newer 7xxx or 6xx cards to show if one really is better than the other.

So it is your choice.

Oh also as far as look are concerned... one of the top reasons I was an idiot in the other thread is because of how bad a universal block looks... well only problem is that once it is installed in your system you see the backside of your card not the frontside so... how much better does it look?

The way the stock cooler works is that it blows air across the card, including the VRMs with heatsinks, so there is a lot of directed airflow going at them in the stock cooler. You might get away with not using heatsinks on the memory but it might cause some issues and make the card last shorter time as the chips run hotter, and you can get them with less than 5$ so why the heck not? biggrin.gif

In the end universal blocks will work just as fine as full cover blocks as long as you make sure everything else on the card is cooled right, and as you are doing this for silence reasons party the full cover block might be the way to go if you dont want that extra fan in your case to direct airflow on the card. Up to you OP wink.gif

If you want to save some cash and want to make your GPU run cooler and quiter i can also suggest after market GPU air coolers like arctic cooling ones. I replaced my horrible ASUS DC1 cooler with Twin turbo II i was able to OC much higher, run cooler and so quiet i cant hear it over my case fans, all at the same time thumb.gif
