The water would already be saturated with heat from the gpu and wouldn't be able to dump it into the air before entering the cpu block to remove heat from that block. just my 2 cents

Yea, this is what I'm thinking. The hotter the water is when it hits the block, the less heat it's going to pull from said block. That's what I've always personally argued, but I really wanted to experiment and test it first hand.

Loop order doesn't matter as long as it is radiator > cpu > everything else. This is common knowledge.

Not as common as you think. It's often stated to people around here that it doesn't matter period. Few people tack on the Rad > CPU > THEN it doesn't matter part. By definition, loop order does matter, if this is the case.

Again, I personally am NOT surprised by the results. This was simply a personal experiment to try to see what the results would be. I have enough tube to return the loop to its previous setup, but had a little time to kill.

That's what logically makes sense to me even though it shouldn't make too much of a difference. Also, is the block tightened down enough? I had my block too loose and it was around 55C load and when I tightened it down it dropped to like 45C under load smile.gif I was quite happy that night lol

Everyone says that but he is definitely getting different results compared to the general rules and standards.

Yea, the block is the same mounting as it was before. I didn't remove it during this procedure.

Hmm weird. Probably would be that the water was already saturated with heat and couldn't absorb any more heat once it hit the cpu block. frown.gif glad to hear that you were able to get it back to its previous state.

really even "Rad > CPU > Then it doesn't mattter" is incorrect... You still need your Res feeding your Pump.

Yea, I am booting it now with the restored setup. I'm going to test it out again and see if the temps are now back 10C lower. If they are, I have all the answer I need.

Edit: Now running Intelburn and checking results. Gonna smoke while it runs, and then we shall see.

it should not differ that much. Even if you switch the loop order around, the water must travel over all the components in the loop. This would make the water in the loop the same temperature throughout the entire thing. Unless your flow rate in nonexistent I don't see how this is possible. And you have no proof. just words.

It all depends on how long you run you system. short term running (less than an hour), you see different temps. which is what you might be seeing. But after extended periods of time, the temperature of the water in the loop is the same.

Refer to this actual test to really understand why:

you might be losing flow somewhere. Again, it's not possible unless you can tell me you've measured the water input temp to your cpu block and tell me it's 10c higher than it was before. The delta for an entire water loop from before the radiator and after the radiator rarely exceeds 2c in total. Give me the facts (ie. your water is 10c higher and your flow rate is measured to be exactly the same as before) and then it's more plausible. This isn't me jumping to conclusions. It's physics based on the specific heat of water and the actual heat output of a cpu is nowhere near hot enough to increase water by 10c in 1/2 of a second that water is touching the cpu sidewall of the block. if your pump pumps at 1gpm then that's like boiling a gallon of water from 0c in 10 minutes from the cpu and I can tell you a cpu isn't a stove burner and even for that a gallon of water is a lot to be boiling.
