This means the radiator is overwhelmed by the components it's trying to cool. Time to upgrade your radiator to a triple or better, or simply add another one. This should take care of it.
not "scalding hot" the radiator on my h50 has never been hot at all .. barely blows luke warm air when im stress testing .

The rad should not be boiling hot , thats not a good sign of anything .. at most it should get warm not scalding .

i think hes pump has died on him , but if it did hes pc would switch off from overheat protection so i dunno .. i know when my pump is not connected my pc wont even boot past the loading screen it will just switch off .

Here's a possible "solution" which costs nothing and is simple to do.

1. Downclock your cpu to 4GHz and lower Vcore. Turn off hyperthreading. Maybe even disable one or two cpu cores. This will reduce cpu heat plus hopefully create a cpu bottleneck which will slow down your GTX 580. i7-2600k @ 4.85GHz is "overpowered" for a single GTX 580.

OR

2. simply turn on v-sync.

Even under load a rad with crappy fans should never get hot to the touch. He has the fins clear of dust and trash. So he has enough air flow to cool the rad.

The problem is that the water in his line is getting to hot, this is cause by the water being in his blocks to long. His cards and processor are heating up quickly and cooling off slowly.

Here is the big issue, we don't know what pump he is running on his system, and he is running it thourgh two blocks and two rads. This is a lot of restriction on a loop, if he is running a crappy pump that can not run enough water through the loop then he is going to have a problem cooling the water.

A rad can only cool so much. The longer the water stays in the block the more the temp rises of the water. now lets say the Rad can only remove 10% of the delta temp. then the water is going to continue to raise until the temp till hit hits a wall.

Now the fastest the water moves through the loop the more heat that can be removed from the water because it cools everytime it runs through the rad after the system goes back to idle. If the water moves slower then its going to take longer for the water to cool.

you definatly dont need more rads , thats silly ... those 2 radiators are more than enough to cool down what you have .

its either : pump , fans or the seating of the block .. the rads have nothing to do with it .

wat rpm is ur pump meant to be working at ? go check it out and let us know what urs is at .

Either that, or get some new fans for your rads.

Hold on just a second, how does this make sense at all? The RAD is hot, which means that the heat is correctly being transferred to the RAD. The heat is already there. The fans are the problem, since they are unable to cool the rad. Take the loop and pump out of the equation. The only purpose of the loop is to bring the heat from the CPU/GPU to the RAD, which it is already doing. Since you can take this out of the equation, now just imagine an air cooler. If the air cooler is hot, it's doing it's job correctly. Either your fans aren't powerful enough or your surface area is too small.

If the pump had truly failed, then the water in the radiator wouldn't be as hot as it should be, unless somehow the radiator magically creates heat by itself when the pump dies. Convection is not an issue here.
When I removed the radiator cap, there was smoking hot water vapor coming out of the radiator. Just because the radiator is hot, does not mean the pump is necessarily working properly.

that wont fix anything , thats stupid advice .. disable cores ? bottleneck the gfx card ?

what does vsync have to do with anything ..

theres should be no problem running either of those 2 overclocked with 2 radiators , the pump has given way .. im 100% sure .

doesnt matter what fans are on it , aslong as there is it shouldnt hit 80c while playing a game ... dead or weak pump .. obvious

But if the RAD itself is hot to the touch, this does not apply, since going by your theory, the RAD should be cool while the components are scorching.

Right, but what it does mean was your radiator wasn't doing it's job either, because the radiator should have been cold if it were working.

Gentle typhoons are more than enough to cool his low fpi radiators.

I think I've explained my logic enough. Although it might not be the solution. But ppl recommending fans and what not are not following. And his two radiators is enough to cool his components depending on voltage and oc.

H50? sorry had to say it.

I think I said enough. Can't wait to see the solution to the op's issue.
