Lian Li PC-70 Air Flow Case mod - Help re-routing Air / dremel and drill to make more efficient. - Page 13

post #121 of 190
The issue is that the 120mm isn't supplying enough air. The problem with your side fans is that they are not position directly at the GPU fans. While using the side fans as intake should benefit temps, it might be randomly dispersing it around the case for other things.

The throttling might be the OC limit of the card? Might not necessarily be thermal throttling.

something like this



could wreak havoc on your GPU temps even tho you can't really see it externally.

That makes sense. I just bought the cut to fit air filter for 99 cents a d a ten dollars torx screw set.

Considering that the fans are inside the case on the side panel What's the best way to install the filter? Attach it to the chrome on the outside? I have nylon on the bottom right now. Do you think I should replace that with this or keep it there?

the side panel is abit difficult to deal with because it did not come with its own filter bracket that you can just put filters in like the front side. however it's possible to buy something like this



https://www.carltonbates.com/Fan-Accessories/MECHATRONICS/Fan-Filter-Kit-92mm-3-62-34-/09362-F-30/p/40026698989-1?mkwid=dLwaCriV&pcrid=37834649954&gclid=CJLep4KZkL0CFUNqOgodDlgAfQ

to house the filter. it doesn't match the color scheme of the lian li so it's up to you if you want to go this route.

alternatively you can get something like this



http://www.ebay.com/itm/like/321096975381?lpid=82

which does fit the color scheme, however you'd have to unscrew the fan each time you want to wash the filter. so you will pretty much need to just vacuum the filter clean if you use the aluminum filter.

i linked the 92mm size because i think that's what it is on your case by eyeballing it. but if it's 80mm size then your selection opens up abit more since the 80mm was a much more popular size back in the day.

for the bottom of the case, you can just Velcro it the way i described before because nobody is going to tip your case over just to look at how neatly you've put your filter on biggrin.gif

and while you have the heatsink/fan assembly off from your titan, you may want to do some dissection of that to see if you can inspect and maybe blow out the dust that's accumulated on the heatsink itself. it should help your temps.

Thanks a lot! I took the air filter and put double sided tape and linked it to the inside of the case since it wont fit on the outside. THe problem with that is that it restricts air flow...... And who knows if the double sided tape will work. I am going to utilize that for the time being until I fix the temperature problem.

Speaking with EVGA they said my temps should still be lower and that if the thermal paste does not work after 48hrs that they want to RMA the card.

I think the main problem is that the Titans take air from the top of the intake fan, which means the 120mm fan blowing at it from the side.... is it really helping?

What the card needs is a direct way to get air like the bottom card has, for that to work there needs to be a way to push air in between the cards. I understand now why people would go for Water cooling.

OC Scanner seems to run really hot regardless of anything, what I want to do is try a +100MHz clock on the top card and a +150MHz clock on the bottom card with a Power Limit +150%.


Let me know if my rambling makes sense 8-)

the airflow restriction from the filter is fine. blower style fan has far higher static pressure then regular fans and overcoming the restriction of air filter is nothing for that style of fan smile.gif (this is the reason why vacuum cleaners use blower style fans ) just remember the airflow restriction you had when both cards were sandwiched next to each other. that was FAR more restriction then a simple air filter smile.gif

i suppose RMA is not a bad idea considering the top card really should be less then 40C and 20% fan speed (default silent profile from the factory) when it's idle.(this really should apply to both cards, but SLi is alittle funny at times especially if you OC it.) the 120mm fan is supplying it with PLENTY of cool air so that's not an issue. the characteristics of a blower style fan is it has VERY strong static pressure, but the actual airflow(CFM) is relatively low. so the 120mm fan is already oversupplying it with cool air anyway.

I'm willing to bet this is more of a dust clogging the GPU heatsink issue more then anything but RMA may be the better option because you don't know what type of dmg you've done to the card back when it was idling at 70C biggrin.gif better to be safe then sorry smile.gif

Now that's the neat thing about EVGA. As long as you still have the original cooler mounted for RMA, they don't care that you took it off. It's kind of a fuzzy warm feeling when modding smile.gif

You could try and see if there's lots and lots of dust in the cooler. If it's clean, the best idea would probably really be to RMA the card. If it's clogged as hell a RMA might also be a good idea. psyclum already said it, you don't really know what the chip has endured in those hot days. That dusty example pic looks nasty

I would clean and use a remote temperature probe to check what the intake air temp actually is going into fan just to be sure.

If you don't have one a cheap indoor / outdoor digital thermometer with wired remote sensor like in case cooling link in my sig works a treat.
