Hey Aaron Are you using the stock cooler on your CPU still and do you have the processor overclocked? If it´s still overclocked no wonder it gets a bit hot in your case with that graphics card too. Fans for an aftermarket cooler for your CPU tested the other day - link here: www.overclockers.com/65-fans-tested-megahalems/Do you have the option of controlling speed on your case fans? If not then my guess is they are not moving that much air if they are the ones that came with the case. What case do you have? I think that recommending a case fan is not the same as for a cooler - how much noise do you want and what are the ones in your case producing now - roughly - and are they very quiet and do you not mind adding a notch since you probably can not hear them for the stock cooler on your 4890? What then if you are not gaming? My case when everything fired up sounds like it´s lifting itself from the Small table where it stands Poul Hey Poul, This is the case i have - www.newegg.com/Product/Product.aspx?Item=N82E16811156135 All my case fans are stock except CPU which is still OC'ed at 4 ghz(well 3.993ghz). I had a guy here in town install the CPU and cooler to the MB(im doing it next time) when i first built this and i remember him saying he didnt use the stock fan with the CPU, he used aftermarket fan which was a little better than the stock fan, but it was not a high dollar fan either, so i could stand to use a better CPU cooler too. To be honest, i have no idea if i can change speed for the case fans or how to do it(in BIOS?) I run the 4890 fan speed at 100% when gaming, which sounds like a mini jet. So the noise doesnt bother me too much. I usually have the TV or music on anyways. My temps are good unless the fans get dusty, then they are still within range, but on the high side. Im more interested in better case fans for now. Also installing 2 more in the front of the case which will then have 5 fans, which brings me to another question - Should the 2 fans i install in the front be exhaust or intake? Working with fans in heating and cooling, i understand static pressure, if the fans are used as intake then the static pressure will be alot higher which will increase fan speed and air flow but be harder on the fans and the might not last as long. If i use them as exhaust, then i will have to drill some holes for intake air somewhere, there are some at the back but not enough. Most fans require 110% intake air for however much CFM they are moving for best efficiency and longest life.

Hey Aaron The two rear fans in your case have a thermal thingy attached on the wire and if you move that closer to where it is warmer the fans will spin up? Or are they all ready running max rpm? I really would like to know what heat sink that guy installed onto your LGA 775 socket motherboard and what fan he attached. Is it a heatsink even - what about a picture? If I remember correctly you have a E8600 CPU? With that one overclocked to 4.0 GHz and running a 4890 graphics card things must be pretty warm in there? What about testing temperatures? Everest Ultimate is a great program for that - free trial period: www.lavalys.com/support/downloadsAbout improving your airflow; Do you not have any intake fans installed? From what I can read out with your case there is the option of installing two intake fans on front - DO THAT NOW. Now what was it with you and noise - no problem? Well then go get two SILVERSTONE RL-FM81 80mm case fans and move air like crazy. That one comes with a fan controller - just turn it on low if you are not gaming. www.newegg.com/Product/Product.aspx?Item=N82E16835220009But I think maybe they are a bit too loud and perhaps it´s best to get two "Rosewill RFX-80BL 80mm 2 Ball Bearing Blue LED Case Fan with Fan Controller Set" - those you can adjust to your likings as long as blue LED light is ok? And they seem to be priced all right too. www.newegg.com/Product/Product.aspx?Item=N82E16835200027I think I might upgrade my stock case fans too. Poul

Poul No thermal thingies on my fans wires and i have no idea if they are running at max rpm, where can i see this, in BIOS? Ill reinstall Everest when i get back from vacation( i leave in the morning, finally!) and take some pics of cpu and cooler. I think i posted a pic of my motherboard in a thread, but i dont remember which one. I dont have any intake fans now, they are all exhaust. The noise wont bother me when im gaming, as long as i can turn them down when im not. Either of the suggestions you posted will work for me. Thanks!

I thought you said you were a heating & A/C man you can't have all exhaust fans..... if the rear fans are pulling air out of the case then air is coming in from the front of the case. The PSU is pushing air out the rear... Just like a car the air comes in the front and goes out the rear..... I have a temperature controlled CPU fan the hotter the CPU gets the faster the fan runs. normal is 2,000 rpm max is 3,500 rpms edit; opps my normal is 2,500 rpm,,, max is 4,500 rpm's here a utility that comes with my Intel MB ...............................................................................................

The PSU is pushing air out the rear... Just like a car the air comes in the front and goes out the rear..... Well... you certainly can have all exhaust fans. As long as you have an opening that the fans can draw air from, you dont need intake fans(this is how some paint booths are designed). Of course, the intake opening has to be at least the same size as the exhaust openings combined, or 10% bigger. If its bigger or smaller it will change static pressure either too low or too high and the fan motors will burn up quickly and/or possibly cause other problems, depending on the application. I do have certifications that prove i know what im talking about.

I can't image a furnaces or A/C unit with all exhaust fans and no intake but what ever.. As far as you're case the air flow is coming in the front and out the rear. You should have an air filter on the front of you're case or some kind of inlet on the front. I have a 3 inch fan on my front case pulling air from the front to the rear. it's blowing air onto my hard drives then that same air goes out the rear. the keyword here is CFM. Light up a cigarette and blow smoke near the front of the case and watch the air flow... ....................................................................................................

Yes you are right Aaron, but you really want to have cool air sucked into the case from the front - traveling across the case. It all depends on your case and what "holes" you have. With more intake CFM than outtake CFM you have positive pressure which is really good if you run high CFM - not so good if your intake CFM is low and your CFM also is low since you might warm up the air before its sucked out again. With more outtake CFM than intake you get negative pressure which is also ok depending on your case. Problem is with more CFM outtake you suck air from every hole in the case along the sidepanels and everywhere else, further the air that just "escaped" might get pulled back in (all ready heated air). In your case with no intake fans in front and no dust filters - well you look in your case and tell me what you think it looks like.
Poul
Maybe you need a new case?

Sunny, old buddy, your funace only has one fan(blower) for moving air in your house. The induce draft motor we have talked about before is only for removing unburnt gases, it doesnt have anything to do with air movement throughout your house. Since you have an upflow furnace, the blower and air intake is at the bottom and the output air is pushed out the top. There is no other fan or blower on any furnace i have seen(and thats a few thousand). Poul, very good explaination. Im not very articulate . The inside of my pc does get dusty, but i keep my house very clean(thanks mom) so it takes a while to get dirty enough that it effect temps. I have been meaning to install some filters(there is an opening at the rear of my case for intake air also, which im going to close off when i install the intake fans in the front) but i keep forgetting about it. I dont need a new case, i can modify this one myself. Its actually sealed up pretty decent except for the intake openings. I think it would be cool to make my own case, i have sheet steel(plus i can get stainless and make it pretty ) and all the tools required. Compared to some of the plenums and duct fittings i have made, a pc case will be a piece of cake. Designing it for max air movement across cpu and video card should be easy enough. It will more than likely be huge, can always use more space. Ill post some designs so you guys can help perfect it. It wont be real soon though. Im off to Florida! Talk to you guys in a week in a half. I might use my phone to get online while im down there, if i can figure it out, havent tried to go online with it yet.

Yea,,, I know that, but that same fan is also pulling air from inside the house to creat a circulation of air flow.. As far as my front fan on my PC it's pulling air off of the HD and the flow of air goes torwards the rear where the rear fan pulls the air out of the case....... with you're new SSD drive you don't need any fans for cooling...

Intel Core 2 extreme X6800 (2.93ghz). ATI HD4870 video card (512MB). Windows XP. I have a 20" viewable CRT monitor, 16" horizontal, 12" vertical. It can run at 2048x1536, but for most games I run 1280x960 or sometimes 1600x1200. I ran the benchmark from 1024x768 to 1920x1440:
1024x_768 - 789.4 fps 1280x_960 - 648.5 fps 1600x1200 - 486.7 fps 1920x1440 - 378.2 fps

Hey I just wanted to tell everyone thinking of buying a new Nvidia card that now there really is something worth buying. Nvidia just released two new SKU´s the GTX 460 768MB and the GTX 460 1GB. The first 768Mb one costs 199.99$ and the 1GB model is around 229.99$ Look here at Newegg: www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007709%20600007323%20600062521&IsNodeId=1&name=GeForce%20GTX%20460%20%28Fermi%29Now these 2 new SKUs are also based on the Fermi architecture, but unlike the GTX465, GTX 470 and the GTX480 it is not the GT100 chip, but a smaller one called GT104. Now I read a lot of reviews on these cards and I really like what I am seeing. The 768MB model is slightly slower than my GTX285 and the 1GB model is just about as fast as mine when mine is overclocked. But these cards have so much more potential for overclocking, because they run a lot cooler and you can add voltage to them within the warranty. Just look at this picture where you see them running stock and overclocked and in SLI. I guess buying that cheap 310$ GTX 285 would make much more sense than buying two new cards, but I really want DX11 for the future. Waiting a few months to see what Nvidia will bring with that GT104 chip is also an option, because the chip in the GTX460 is not using its full potential, because it runs with 336 Shader processors but in reality has 384 Shader processors - so expect another faster one in a few months. Like always - buy now or wait for something faster? Maybe I ought to explain that buying new graphics cards like a GTX 460 is a hell of a lot more expensive to do in Denmark than compared to the U.S. I really do not know what to do. Buying another GTX285 and running in SLI or buy two new GTX460 and run in SLI. Maybe just buying another GTX285 is the way to go - since I can match the performance still and I am actually not in need of DX11 at the moment. Just it would be fun to have something new to play with. Poul

I just tested my GTX 285 compared to that GTX460 1GB "Golden Sample Goes Like Hell" card and mine is much faster. Damn it - I guess running two overclocked GTX 285´s would be better - and cheaper untill something better comes along. I will order that cheap card and see if it is as fast as my own. Here the GTX460 is running Furmark 1.8.2 benchmark and below is my results when set for stock speeds and when overclocked. Furmark 1.8.2 if you wanna test your card: www.ozone3d.net/benchmarks/fur/The GTX 460: Mine at stock speeds: Mine when overclocked:

Usually I would not advise buying second card, if your current one is too slow, but in this case I would buy another GTX285.Fermi is not convincing at all since you would not really benefit of it:P Also Nvidia seemed to have solved the microlags during the gameplay, at least, it's worth a try, if you arent convinced, just refund the newer GTX285;)
