I just want it to run cool.I recently installed my AMD 955 be with the stock heat sink and couldn’t get it to idle at less than 53 degrees Celsius after 1 level of Left 4 Dead would be up at 60 degrees Celsius on all 4 cores. I opted to pick up some Arctic Silver 5 and cleaned off the heat sink and cpu very well with some Arcticlean 1 and 2. I used a couple coffee filters to clean the CPU and heat sink off and applied a small bb of arctic silver 5 to the center of the CPU core and put the heat sink on it and wiggled it a bit to relieve any air bubbles. Clamped it down and it’s been about 4 days now and it would idle anywhere from 46-52 degrees Celsius and it still will go up to 60 degrees Celsius after 1 level of Left 4 Dead. So I ordered the Sunbeam Core Contact which I’ve heard good things about and did the same thing with that. It would idle around 38-42 degrees Celsius but go up to 60 degrees Celsius after 2 or 3 levels of Left 4 dead. I’m not sure what to do now. I have been thinking about ordering the Zalman 9900 because I’ve seen good things, but that’s the same case with the Sunbeam. I want something that will utilize the stock heat sink retaining mechanism since I don’t have access to the back of the mobo. I’m not overclocking the CPU and don’t plan on overclocking it, I just want the thing to run cool. I've got a 200mm case fan for the intake fan in the front of the machine, a 180mm intake fan on the side, a 200mm exhaust fan, and a 120mm fan blowing on the hard drives. I'm not sure if the fact that I have 2 4850's in crossfire running in the mid to high 70's would be killing the heat as well, but I'm at a loss and have no idea what to do here. It was 87 outside yesterday and extremely humid which may also have something to do with it.

Also, just to add to my post, even taking the side panel off and having a house fan blow on it did literally nothing to the temps.

Hmm, As u said that there is so hot and humid outside so that may be the result in increased temps of ur CPU. AS5 needs 150-200 Hrs curing time to work on it's full potential. Have u mounted ur heatsink properly?

Yes, I remounted both heat sinks both times I placed them on the CPU and had the same result each time. :fou:

I hope u have faced the heatsink face on the rear side so that rear fan can blow all the heat outside the chassis. Could u plz explain me that how many fans ur chassis has and where u put all the fans in ur chassis?

Yes, I faced the heatsink facing the rear so the fan blows towards the back of the case. I have the intake fan below the hard drive cage, the fan on the side panel to bring in air through the mesh, and the exhaust fan next to the heatsink. The picture below is my desktop minus the water cooling setup. There is a fan where the radiator is on this though.

U are using 2x4850's in CF mode and u are using Referenced design 2x4850's and 4850 used to known about it's heat, so i think this can also be the problem. One of my friend has also bought MSI referenced design 4850 and then he changed it's heatsink with the Aftermarket Thermalright VGA cooler soon and then all the things have gone right.

They are Visiontek Radeon 4850's. I do plan on upgrading to a Sapphire 5850 so was hoping to stay away from a heat sink swap on the 4850's.

I have used ATITool to keep the fans on the cards up around 50% during gameplay and it will drop the VGA temp down to around 56-59 degrees celcius yet the core temp on the CPU will stay at that 60 degree celsius temp. Do I have to get the temp on the cards down into the 30's or 40's to make a difference then?

If ur Graphics cards temps are under 60 while playing games so there is no problem then. My CPU used to idle at 40 degree at 3.6 GHz from 3.0 GHz and while playing game, my CPU never crossed 50-55 degrees. and My GPU's idles at 46(GTX 275) and 60(8600GT)

Hopefully this Zalman will help along with running the cards fans at 50%.

I'll update this Wednesday or Thursday after I get the new heatsink installed.

*UPDATE*

I got the Zalman installed today and am now have an idle of 36-40c and max load on Prime95 heat test of 53c. This is in a room of the house that is not air conditioned and is pretty humid, so once I move it to another room that is air conditioned I'm expecting another 3-5c drop in temp in both idle and load. :bounce:

Congooooo so Zalman did the trick :D  , but sunbeam CCF 120 is also a gud cooler.
