Uh

What? no.

The PSU intakes fan from outside the fans, Idk how your side / front fans are setup

But either way the radiator is on the top-rear [rear of the case, near the cpu] and blows air out.

After getting some temp increases ive decided to pull the card apart and check to see whats up.
Here is my current setup. Rad intakes some freshy from the bottom but exhausts into the case.


The hoses are so short with the H70. With the ninety angles coming out of the pump it makes it hard to place the pump on the card. Ive had to go with one line in front and one line between the card and mobo. There is not much space, I see the mobo flex a lot when snapping the card in place. I could just remove the shroud but I like the look this way.

Here is what I mean, the naked card (dusty I know, its been close to a year since removing this card) and how the pump and hoses sit.


At first id thought the zipstraps were backing off which were causing the temps to increase. Could have been something to do with it, the pump was a little loose and was never completely tight to begin with, it always had some wiggle room. The shocker was how badly the tim had degraded ... better yet.. moved. There were sections of the chip that were completely void of tim. The tim had oozed out and was running down the sides of the chip, pooling around the edges and onto the pcb.




The bottom of the pump showed lots of wear, tarnishing, whatever you call this. Ive not seen this on any of my pumps prior to this time. Ive used these on my cpu for years and better than a year on several gpu units.


even after cleaning the tim off the pump the pump still showed badly of stains


I had to use some 1200grit sandpaper and then some 4000grit to get the pump back into shape. Its not as mirror finnish as the pump unit sunset1 sent me but it will do. Originally the unit sunset1 sent me was going to be used. I have been lapping the pumps for a week or more now on that unit and they look pretty nice.. well one does, still have one to go. The pumps have straight lines coming out of them. I could run the lines directly out the back of the card and mount the rad against the optical bay/hdd bay wall. I ran into one issue and that is that the pump that will sit on the chip does not have connectors im used to on these units. Ive tired all sorts of ends to plug into the pump but nothing works. The second pump has normal connections but it also has ninety degree angles coming off it so its no different than my H70 im using right now. I am going to try to switch the pumps on the unit so the pump with the normal power connections will have the straight barbs coming out of it. I will just leave the second pump hanging, tuck it away/hide it or perhaps put the stock gpu heatsink on it and leave it there as addional passive cooling. Regardless I now have to look at cutting the lines at worse. Thanks sunset1, free makes the cutting not so hard lol thumb.gif

Ive put the card back together again with the H70 unit. The line against the mobo and card is bent worse than ever now, pump has started to gargle water. Pretty sure ive restricted some flow but the temps are back to where they should be for this card. Im going to live with it for now till I can prepare the unit sunset1 sent me. Dumb luck would have it the gpu bracket off his unit is a perfect fit for my non reference pcb. Like dead eye perfect. Love it. The same bracket would not work with my 560ti. I lined them up and they were not even close. Nice, have my pump attached using a bracket. Super solid and no movement at all. Even got to use compression/tension springs for mounting, just like stock.

Idle 21-24c. Max temp (only done these photos in cs6, no gaming temps yet) is 27c and the house is 75c currently. I do a startup when the house is cool over the night. Im hoping for sub 20c.

I will post pics later of the mod once ive modded the other clc for this card.

Were you using the stock H70 tim?

+REP, thanks for the very informative and well-documented post

Id have to check the tim I used but it was not the stock paste. MX if I remember, not sure of the number though, its all put away now. Its good stuff though, not future shop garbage biggrin.gif Kidding, future crap paste gave me my best temps ever but it burned out very quickly. It was a silver based product.

Thanks for the plus reps thumb.gif

No. What I was asking is if I install my radiator/fan setup in the bottom fan slot exhausting hot air towards the bottom of the case. With that, the hot air will spread out outside in the bottom part of the case and then it will combine with the ambient fresh air that is ingested by the PSU fan (which is also in the bottom area of the case, yes outside), side panel fan, and front panel fan. Do you get what I mean? Lol.

I think it's negligeable to be honest, you have 2 fans pushing air straight up...

Your PSU will be fine

Interesting to note. I wonder how CLU and IX will each hold up thinking.gif

What do you mean 2 fans pushing air straight up? I thought the airflow of the rad should be exhaust in the bottom of the case, which means downwards out of the case?

It depends on which you care about more ... case temps or rad temps

If you want the rad to be cooler, than intake cold air from outside

If you want the case temps to be better, exhaust warm air out the bottom

Personally I would have it as an intake ... that way PSU is cool anyways, and the rad gets the best temps

if you have a side fan pointed at the motherboard, plus the other case fans, that should give it some nice circulation
