Help me optimize my airflow ! - Page 2

post #11 of 56
So I see you got it figured out thats great, but just for future reference this is the problem with water cooling only 1 component. You have to sacrifice gpu temps for better cpu temps by intaking rad, or vice versa. I know CLCs are neat and easy and people think they're really water cooling with them, but imo they cause more problems than they help.

Really water coolng one component is not the problem.
Most water cooling systems do not water cool everything in the system.
Really, CLC's only have one thing in common with real water cooling .. the extremely small amount of water in them.
  • CLCs have pumps that use the same or less power to move coolant than most fans use .. compared to real water cooling pumps that use several times as much power.
  • CLCs have a really poor quality radiator that depends on extremely dense fin count and high airflow rates to cool
  • The total weight of a 2x 120mm fan CLC without fans is less than just a bare empty 240mm component radiator .. complete system weights less than bare empty raidiator with no coolant, no fittings, no hoses, no pump, nothing.
You compound this with people buying CLCs and believing the advertising hype of lies that say to install them as intake instead of exhaust and you only show how little you know about cooling and airflow.

A couple of us were just reminiscing about how years ago Asetek did a 'report' of how much better things cooled with radiator as intake rather than exhaust .. and how their own test data showed how wrong they were. But people like you seem to to eat it all up and beg for more. doh.gif
But I do agree with you on the 'imo they casue more problems than they help. thumb.gif

Replace your GPU thermal paste too, with MX-4 for example. Temps may drop about 5C more.
I replaced the stock thermal paste on my Gigabyte 7970 WF3, and temps went down 5C. The stock paste was chalky and dried up biggrin.gif

It is a brand new card. I wont open it, I think I also lose the warranty.

I don't think so, if there arent any warranty void stickers on the screws.
As long as you don't damage the PCB, it should be fine.

GPU paste is not an issue. There is usually a warranty sticker on one of the screws.

Slot covers are not an issue if you have more intakes fans than exhaust fans. You could put one of the side panel fans on blowing in to make sure air is going out of the slot covers rather than being pulled in.

While there may be cases when replacing GPU TIM is not a problem (or the PCIe slot covers) there are many times they are the problem or at least part of the problem.

None of my GPUs have or have had any stickers restricting the removal of cooler to replace paste. That said the stock TIM is usually good for the first year.

Back slot cover removal often lowers GPU temps by allowing airflow or more airflow front to back around the GPU. Even vented slot covers are still restrictign at lest half the airflow.

Should have been more clear, removing the back covers is not an issue w/r/t dust if you have a positive air pressure setup.

I know it's nit-picking, but I've seen cases with much more intake fan flow than exhaust, like no exhaust fans and 3x 140mm TY-147 fans spinning up to 900-1100rpm at load, where the PCIe covers were flowing air into case to back GPU fan when GPU fans were running at speed /working hard. The short distance from back openings to nearest GPU fan combined with GPU fan closer to front of case pulling in air means it is often 'path of least resistance' for airflow to back GPU fan. So back fan pullsl air from GPU slots easier than from what air is getting past next fan on GPU inside of case. Hope that makes sense.

OK, hold on. There is a lot of hate for CLCs going on in here and I agree with some of it. But, CLCs on GPUs are actually extremely beneficial.



If a 40C decrease in delta over ambient load temperature isn't worth it...this particular design uses an AIO + traditional blower. 40C! You could use 100 Delta's ziptied to the GPU and you would never get close. The entire design principle of traditional GPU cooling (whether blower or fan-based) is flawed. There is simply not enough cooling potential that can fit inside two PCIe slots.

The common cons: "the GPU VRM/VRAM!" - spot cooling is always effective, as seen in the EVGA Hybrid linked above. "Radiator placement is bad" - if you're concerned with radiator intakes putting hot air in the case, which I agree with...you can flip them to exhaust out the case. Sure, then the "ambient" for the radiator intake is now 35C (inside case) instead of 25C (outside case). I don't understand how alone completely detracts from the 40C reduction in core temperatures.

You all realize that GPUs are the hottest components inside most gaming PCs, right?
