I think may differ due to different case designs. but for my experience, most casings gets better airflow by pulling air out of the case since the hot air inside being sucked out. the front intake will serve as the air pull into the case. if installed the other way round, fresh air, or most likely our hot ambient air (in non air-conditioned room) kept pushed into the case, making the temp higher even though you have exhaust fan cause it is not able to pull the air out fast enough. just my 2 cents. 

i think there are no guarantees, you should just try out yourself and gauge the temp to see which is better, since its a simple job of reversing the fan mounting only.  my rig overall temp dropped 3-4C by using this method, verified by kabukiawie, lol. 

as for your 9800pro, 65C during load is normal, that card is a heat monster. i highly recommend you get a better cooler to tame the heat. 

too bad in p4p800x the pat settings is really limited. hmm...... hows your p4p800x pat setting?? share share...hehe

i have see the boost in sandra memory benchmark with PAT enable. others hardly see the different.
i see. btw, you are running 1:1? 5:4?? ofcoz for your p4p800x. as a reference.

oh? any changes?? can oc more??

@raymond
hmm....its really sweet as you are running 4 sticks of ram and still manage to rock that high.

like what edministrator told me, his p4p800 is holding the ocability coz of the 4 slots of rams. 2 stick is stable and full slots is not. your bt-j really a gem. if you using ic7 instead of p4p800x, 3.5GHz is not a problem.

have not tested the oc yet.just fixed all the stuff in and waiting for the ceramique to break in. at least now i have the option to push the vdimm up to 3.3v and vagp to 2v 

VAGP of up to 1.65V is useful for stability of some graphics cards and provides for better stability under high FSB operation.

I guess overclockalbert has help me out from my doubt.
@pengster
Well i would say in long run it will benefits. I myself not really test the difference from a low VAGP and high VAGP, but since it is proven I guess it is better.

Back from a long run outstation work! Hm.. About upping the vAGP, i do try before with my system. I dont know whether is true or not but i do feel the stability of increasing it. i upped mine from 1.5v to 1.6 and i could prime my rigs in 3.65Ghz, 1:1 ratio with Orthos priority 10 for 5hrs without shutting down. Before increasing the vAGP my system failed on priority 10 priming after 30mins priming.

Thats what i feel by upping the vAGP!

hmm....it seems that now everyone is busying playing with vagp. I am out from the party...

@raymond
what vcore you use for your p4p800x?? i mean you set in bios. i currently set to 1.575v. dont know safe or not. hmm....temp is not a problem.

For my board, increasing Vagp does help stabilise FSB. But most overclockers say that ATI graphic cards are very sensitive to voltage, because it puts more stress on the MOSFETs on the card.

To add salt to the wound, I replaced one of the MOSFETs on my 9700 PRO with a lower quality version because one accidentally got ripped out when I pulled the heatplate off

I just changed to a new LianLi aluminium case yesterday, temperatures definitely have dropped since my old casing. To add, I'm lovin' the brushed aluminium

But since my new casing has no sideport to blow cool air directly to the processor, my processor fan rose from 2700 RPM to a warp-speed 4500 RPM! It spins so fast till the whole casing starts to rattle and vibrate. And to add, the fan now sounds almost like a tornado inside...

wao....got lian li already.

you using stock hfs?? stock fan really expert in making live hardrock concert in your casing. damn loud.
cool, stock vcore manage to go till that far. now i just running at 242. really hope that it can stable at 250 but too bad. 3:2 can go till 250, but performance really sucks.
