i just recently applied my video card and cpu heatinks with Artic Silver5 because people are saying theyve gotten 5*degree drops and i ...pretty much didnt see a difference..

my fan setup is this: a 120mm fan + 80mm fan sucking in air from the front...and 80mm fan sucking out from the back and/removed pci slot covers to aid in the removal of air... ive messed with different setups like the 2 fans in the front sucking out air and i didnt see a difference my cpu has a Thermaltake Sonictower..which is basically a huge 110mm fanless grille...and it didnt seem to make much of a difference either

out of bordem and couriosity, ive tried taking off my side panel and using one of those 2ft room fans.set it right next to the case to suck out air/vise versa and it made no difference either, even on the highest speed setting. wtf? [which is really loud btw]

im going to buy a Thermaltake Big Typhoon because of the large amount of great reviews from it...i really hope thats gonna help T_T

i hear about people getting 25*degree temps on their comp with just fans...are they lying or they just have good fans?

I don't know about these cooling systems but i can tell you that i changed the coooling system of my 6600 GT with a zalman and set it at full speed (rather than less noise) and i can see the difference; the temperature is lower.

May I ask why you want your hardware that cool? Chips are performing better at slightly higher temperatures (40-50 degrees), due to speed loss by temperature.

Anyway, if that's what you want, it's fine with me. About the ThermalTake Big Typhoon, I'm still very happy about it even if it's VERY big. With normal processor use, that cooler is keeping your CPU just as cool as your case. Which is about 25-30 degrees on avarage. Though, after 2 hours of intensive gaming (which I do), the temp. is raised to 40-42 degrees max. So you bet it's a good cooler.

For the record: the temperature 'limit' for a CPU is about 70*C, most standard system CPU's hit the 50 degrees at avarage. So don't worry about the temperature too much, be happy with your 38.

hmm so 38-40 is pretty normal for an overclocked pc? [probably the wrong forum to ask]

yeah like when im gaming for lets say about 2 hours....ill look at the temp and itll say 50*+!!!! yes my cpu and video card are overclocked....and i dont want to lower the clock speeds because its performing pretty badass....

i have yet to have restarting problems do to overheating so i guess thats oks T_T well thanks for the info anyways :D

When my cpu is not overclocked my average speed is 42°C with a cooler master fan (not very expensive one and rotates only at 2500 RPM) and 49°C at full load. When overclocked it rises about 8-9°C max in summer (more hot).

Anyway, i remarked that changing the tower helps a lot; i explain :

Before i had a smaller tower and leaved it always opened (without side door)and the overall temperature was more hot and now i've got a bigger tower (Antec slk 3800 - everything else the same) and it's less hot when closed !!!

Also because the airflow is more fluent and it helps a lot.

So may be it's your tower that is the source of this high temperature because there's a bad flow -> less cooling.

What chip do you have? In any event, if properly applied AS or more air flow doesn't decrease temps, then your bottle neck is the heatsink. Look for something that has more conductive material and/or more conductive surface.

Saka is right about the airflow, I actually fogotten to meantion that. Considering you have a fanless T Sonictower, it is an important issue.

a 120mm fan + 80mm fan sucking in air from the front...and 80mm fan sucking out from the back That'll do the trick indeed, assuming your PSU is working as exaust too. Mind the fact your airflow is gone when opening the side panel ^_^. Anyway, the best is to keep your panel closed and make sure you haven't got too much cables running right through your case blocking the airflow. As Saka meantioned, a bigger case provides more space = better airflow than a smaller one. Myself, I got a 120mm intake fan at the front, a 80mm fan at the side window supporting my Vidcard and another 120mm fan at the back, which works together with my CPU to suck the air out. Keeps my most important hardware cool (CPU, Chipset and Vidcard), but because there's still a mess of wires in my case, my DVD drives are getting pretty heated sometimes, 'cuz it's out of range for the fans to cool. Still need to find a solution for that.

Are you using AMD's cool 'n quiet feature? Is it turned on in the BIOS? Basically that will keep the cpu at a steady temperature rather than at its coldest temperature...

this is basically the small ass case that i have hahahttp://www.newegg.com/Product/Product.asp?Item=N82E16856110043http://img.photobucket.com/albums/v94/mtlsharpnel/mtl-complayout.jpg

it has these 2 vents on the side panel...and im not too sure if thats to let hot air out? or let kool air in? should i put a fan there.....actually a fan wont fit cuz my heatsink, as ive said before, is 110mm tall! its less than 1cm from the side panel!

ive replaced the hard drive and dvd drive cables with ones that are a single round cable and it looks alot nicer :D oh yeah and i lowered the hard drive to the lowest slot because space was so tight in there...and plus it let me fit a fan right above and below the drive so it would be kooler...yes?

i have mixed thoughts about Cool and Quiet because it makes my fans run less than 1000rpm..which the indicator turns red? i dont think thats good...

im thinking of drilling some holes in the top haha maybe would let some air escape

Oh lol, your CPU cooler is just as big ass as my TT Big Typhoon. Yea, it doesn't fit that well, does it. Now I it and read a review about my Sunbeam Trio case, where they explained the option to flip the side window, so the fan would support the vidcard more, plus doesn't interfere with the CPU cooler anymore.

Also, in my experience cool and quiet doesn't matter that much. Only with big noisy CPU coolers this option will reduce the noise and controls the temp. better, but with a fanless cooler and normal low noice fans.... it doesn't matter. By the way, my motherboard sometimes yells the CPUfanspeed is too low, while she's controlling it herself. Lol. Pretty stupid.

Chips are performing better at slightly higher temperatures (40-50 degrees), due to speed loss by temperature. O_o where did you read that? The lower the temp, the better (and longer) the chip will perform, though speed increase is very, very marginal. Resistance of the copper tracks in CPU's at higher temps only increases, not decreases. MTL, there is a big chance that you have applied the thermal paste incorrectly - more of the paste than neccessary only hurts the thermal transfer, and your temps could even increase, not decrease, after incorrect application.

haha actually i think i did apply it correctly... i put a little bit on...then i smeared/flattened/buttered it up with an old card.... doing that supposedly makes it actually flat and better contact with the heatsink....did the same with the heatsink.... the heatsink was already lapped btw

well its no biggie....tho i dont think i would go to extremes such as water cooling unless it becomes cheaper in the future like $100 total for all parts.

Did you wipe the cpu/heatsink with high-purity alcohol/acetone and a good, lint free, cloth? You need to wipe the surface of the *heatsink* (not cpu core) after applying AS5 thermal paste, if you only spread it around without wiping off you made the layer WAY too thick (not that it's really neccessary to do that, if the heatsink has a mirror-like finish). Also, temp can drop a few more degrees after a few days of intensive use (heating up/cooling down).
