i want to know if i get 4 more fans, would i be able to oc my cpu much further.. i dont want to go into watercooling yet.. the case i am using is COOLER MASTER Stacker 830 Evolution, i have 3 120mm fans already..(top, front and rear) i can add 4 more to the right side of the case.. i oced my graphic card at a stable speed..
thanks..

I haven't played with overclocking in a while. But I know that cable management is one of the best ways to get some good airflow going through the case. That's usually the first step I always took, since adding fans won't do you any good if you have poor airflow. Also making sure that the environment it is in is cool. Getting an after market heatsink and CPU fan will help more directly with the overclocking. Unless the case is getting really hot, but chances are a better heatsink and fan combo is more what you are looking for.
Goranpaa will be around soon to give some recommendations, I'm sure. He's the king of this stuff as you might be well aware.

this is a really nice one but pricey

that reminds me any one see the ocz hydrojet at the computex
and the ocz headband that lets you play games whit your mind.
pretty cool stuff

well i have ARCTIC COOLING Freezer 7 Pro.. and the cables are in a good place... i got good flow.. i got my cpu up to 3.4ghz(stock is 3.0ghz).. i would like to hit at least 3.6ghz.. i got to 3.5 but it got really hot and unstable.. maybe more cooling.. but i guess your right ill wait till Goranpaa or another ots comes by.. thxs

Hi!
Well, adding more case fans to the Stacker wont make that much difference for over clocking.
But the actual fan configuration, in the respect of having more or stronger exhaust fans will.
Anything in the case cooled by the ambient case air, will be affected if the hot air stays too long inside the case. Side fans can be both a blessing or a curse. Too many / too strong side fans can interrupt, or at least disturb the airflow from back to front of the case. As the air pillar from the side fan(s) bounces against the mobo and create mini vortexes that will have a negative inpact on the cooling. You get almost the same effect as you can see when a helicopter is hovering over water.
If you wanna have side fans? make sure they are low cfm. Like the Aerocool Turbines you bought.
Also as FadedMaster points out, the cable arrangement is important.
And the room temp of coarce.
I'm a little bit surpriced, that you say the E6850 gets hot and unstable at 3.5GHz. As I have read about people with this cpu, beeing able to oc to, or near 4 Ghz without much problems.
But the overclocking ability, also have to do with how good overclocker your mobo and RAM are?
And also, from 2.4 to 2.6GHz will just give a minor improvement in performance. Let's say about 5 FPS in games for ex. The exsperienses I have made during the time I have been fiddeling with overclocking. It seems like each 400MHz oc increase is the only worthwhile overclocking steps. While a 200Mhz oc have'nt done much for the performance.
I guess, that if you wanna over clock much further? Then you maybe are looking at water cooling. Or if you wanna have some very serious cooling? The Phase shift cooler aggregates like Asetek VapoChill LightSpeed. But it will cost you a bundle.
But ask yourself fist if it's really worth the pretty high cost for a good water cooling system like Danger Den or Swiftech? And then all the jazz with slabbing with anti algae fluid, bleeding the system for removing air bubbles and stuff? And also count in the risk of possible leakage.
Your Freezer is a good cooler. The heatsinks Shady suggested are very good ones too
But the question is, if swapping the Freezer for another air cooling system, will give you enough cooling ability to reach 3.8Ghz for ex?
I belive the only air coolers that may give an increased oc ability are :
1. Thermalright Ultra-120 Extreme with the Noctua NF-P12 120mm fan. Another good fan is the Scythe Slipstream, SY1225SL12M (1,200 rpm version)
The Thermalright Ultra 120 Extreme, is the best air cooler on the market.

2. Tuniq Tower 120
http://www.newegg.com/Product/Produ...N82E16835154001
3. Scythe Ninja Plus rev. B with a Noctua NFS-12, 1200 rpm fan. Or the Scythe Slipstream above.
http://www.coolerguys.com/840556035572.html
http://www.coolerguys.com/noctua120.html
The NFS 12 fan, only works with heatsinks with large space between the fins. This due to the different blade angle.
But have in mind that both the Thermalright and the Tuniq Tower are very heavy. So be very careful when moving the pc if you buy one of these.
All the 3 heatsinks, requiers motherboard removal when mounting.
And in the end. The E6850 is a blazing fast cpu, even at stock speed. At 3.4Ghz ....well.
Do you really, really need more oc? If it's gaming performance you are hunting? Consentrate on oc the video card instead. Or maybe even get a second 8800GT?
Edit. Different mobo bioses may give better or less good oc abilities too.
But when flashing a new bios. Always reset the present bios to defaults first.
For ex. My Epox socket 939 mobo, in my second rig overclocks best with an older bios from late 2005.

hmm i project i wish to do besides my Murphy bed in the closet is...
get a http://www.newegg.com/Product/Produ...N82E16896741011
but a mimi freezer
and make a air tight mini plastic case(to avoid any condensation or other damage to the parts) that has one vent to the out side of the e fridge. Then , use all passive cooling but one fan(one one both sides of the vent)..then idk face the case on the side and fill it with dry ice. the only problem is making the air tight plastic case that goes in the freezer.

The mayor problem will be that you need to have both intake and exhaust fans in both the case....So it wont be airtight any more. And then intake and exhaust for the mini fridge too.
But if you can find a way to keep the temperature steady just over the "dew point" Wich is +3C I think.
You may not have to worrie about condensation. But it will be one hell of an achivement if you can succeed doing this.

Thxs guys for the info.. I looked into the bios to see if I update it maybe it will work.. But made things worst.. It only let me oc the cpu to 3.2ghz.. Before I had it at 3.47ghz... I am going to buy a new mb and buy one of those heatsink..
Till then how can I downgrade my bios to a older one..?
Posted by: goranpaa
O.k. That whas what I meant by different bioses giving different oc results. Didi'nt the flash tool made a back up of the old bios for you?
Othervice, go to MSI home, and check the bioses there.
Download the bios manually, and load it into your bios flash tool.
Just make very sure you get the correct bios for the correct mobo!
Dont forget to reset the present bios to defaults before flashing now.

I like the idea of the airtight case. See if you can dig up a really fine mesh screen to catch the dust particles too that's easily removed and no more "dusty case"
