Which PCI case fan? - Page 2

post #11 of 26
A) I think adding a PCI slot fan extractor might not provide desirable result. See pic 1 below. The close proximity of its fan to the central intake fan of the Asus HS5850 DCU Top would likely to cause air competition between them. That is the orange oval region.

Additionally, hot air exhausted from card's front might make the U-turn toward the PCI slot extractor but gets sucked in on its way by the card's intake fan. Note the red arrows.

Anyway, as you have already ordered it, I suppose there is no harm to try to see if it provides good result.

B) I propose an alternative which I think might be better:- See pic 2 below.
a. As the HD5850 exhausts half of its heat via its front, this heat could be better extracted upward via the case top

b. Place an Antec Spot Cool (blue little rectangle) to direct the hot air to rise up towards the case top exhaust fan (larger blue rectangle)
This fan is important because if it is absent, hot air will likely be sucked through the 212+ by its push fan. Obviously not very good.

c. Orient the 212+ vertically so that its exhausting upward as well

d. Rear case fan setup as exhaust and spin slow enough as not to take away fresh air reaching the push fan of the 212+ and not to allow hot outside air seeps into the case

e. Side panel fan to be setup as strong intake to provide air to the HD5850 and the 212+

f. Case front fan as intake as well

Um, wow thats one of the best answers ive ever received.

All of those solutions are very good, but my HD5850 is on the bottom PCI-e and my GTX 275 is on the top (bottom is lane 0 and top is 1) so im not sure how these suggestions will do.

everlube is generally a bad idea, i've had few of them from different companies and they all leaked in one manner or another. the ones oriented horizontally at the top of the case made the largest mess of all.

I do not see any advantage of putting the main card (Asus HD5850) to the lower slot.
If it is a single card setup, that slot runs at x16 (vs x8). But frankly, x16 and x8 do not give a practical difference unless you are a serious benchmarker. Perhaps 2% difference in game framerate.
For a dual card setup (HD5850 + GTX275), both the upper and lower slots will run at x8.

If the GTX275 goes to the top slot, its intake fan (being closer to the card's front) is likely to intercept the hot rising air coming out from HD5850's front. So, this is no good.

Instead, put the HD5850 to the top slot so that its front air exhaust will rise up due to the direction of the Antec Spot Cool. It receives its air intake from a strong side panel fan.

The GTX275, being in the lower slot, will receive its air from the case' front intake fan which is also responsible for supplying fresh air to the PSU. See green arrows.

The vertically oriented 212+ receives its air from a strong side panel fan and exhausts hot air via the case top.

You are a PRO at this, i am LOVING that setup, and i dont know how but you got the lines to match PERFECTLY with the locations of my stuff, even got the fans on the 212 right (thick one at the top while my old thin one is at the bottom) tomorow i will make my 212 vertical and switch around my graphics cards.
But i do not have an Antec spot cool and all i have it the two front intake fans (undervolted) so will that affect it at all? And should i cancel my order on that PCI slot case fan?

Also will the CM 212 fit in my mobo sideways? Because i think it might bump into the RAM

I would have gone with the EVERCOOL SB-F2 it has same CFM and less DB noise than the other

I see that you have 3 concerns. And I will address them individually below.

1. If you still can cancel the order of the PCI slot fan extractor, do so.
Instead, order the Antec Spot Cool. It is paramount to deploy this device (or a similar fan) in such a way that air exhausted from the HD5850's front be directed upward (i) towards the top case exhaust fan and (ii) with enough velocity.
If not, these hot air will be sucked into the 212+ by its push fan.

2. For the current undervolting of the 2 case front intake fans, I suggest to keep the top one undervolted but run the lower fan at full speed.
The reason:-
a. if the upper 120mm fan runs at full force, it is likely that its strong incoming air current will run directly against the hot air exhaust from the HD5850's front. This head-on collision of the 2 airflow paths is no good. Therefore, keep it undervolted.

b. the lower 120mm fan should run at full speed because it provides fresh ambient air to the GTX275 and the PSU. Full speed ensures maximum supply of ambient fresh air.

3. I do not expect a vertically oriented 212+ (with push-pull fans) on your motherboard (Asus M4A89GTD) with Gskill Ripjaws RAM will have any conflict.
Another member (ztmike) has exactly the same combination (motherboard, cooler and ram...well, you have blue and he has red...lol) and he has no problem at all.

Edit 1:
As a side note, since the Antec 300 does not have a fan opening on the side panel over the CPU area, you might need to have a good strong fan at the side panel lower position to ensure good air supply to the 212+.

yeah PCI slot fans are junk

o my, i have my work cut out for me.
Re-volt my lower front fan
Re-arrange my GFX cards
Vertically orient my 212+
Clean up cables

But i do not have a side fan on my antec 300 because i put a plexiglass window there, and i cannot get the antec spot cool because all i have is a 10$ giftcard and its like 14$ .
With that in mind what is my best course of action (10$ limit)
