CPU Fan flow

[ViRaLRuSh]

Which way does the air-flow for the HSF on a cpu? I have been getting idle temps about 60 C and I was wondering if it should feel like it flows out or in. Cause it seems to be flowing in, from what I can tell and it doesnt seem right to have hot air flow like that. I ordered the SVC GC-68 with the fan preinstalled on top of the HS. Those goons might of put it on the wrong way.

Your HSF should be blowing air into the chip, so that is fine.

Are you using thermal paste? If so, you might have too much. You don't want it to drip down the sides of the chip. Also, it takes a few days before the paste is completely set, although that shouldn't account for a huge difference.

I seriously don't even know if the store used paste or not. Like someone said, probably toothpaste lol. But yeah it has only been a day, so it may not have even set yet. I'm gonna call this guy tomorrow. Anyone else know how I can keep it a bit cooler till then? Or if running at 60 while running a game for the next few days is ok.

Which processor do you have? You can look up the specs (temperature tolerance) of your processor to see if you are within its limits. Here is a link to Intel's spec finder Link

List down ur spec. It would be good to know the CPU & mobo u r using. Newer type of mobo could read the CPU temp from the internal diode & not thru thermistor socket.

If the temp is read within the internal diode...60C seems OK to me.

Athlon XP 1600+ not overclocked at all. Shuttle AK32 Motherboard with 256 DDR 2100 Ram. Anything else needed?

any got the limits for this? Anyone? Anyone?

Something you also might wanna consider is if your temperature readings are accurate. I had an Abit BD7-II that showed temps about 10C higher than they really were. 60 is too high for full load, let alone idle. I would make sure your heatsink is actually making good contact with the CPU. A bad application of thermal paste can make temps a bit too high, but only by a few degrees in most cases.

I was just told by a local store to put my case siding back on the case and to see if that helps, since the siding off would cause airflow problems. I think they are dumb for this, but I could be wrong also. Any more suggestions? I mean even though the fan is ~2700 rpm it still should be cooling just fine since I'm not overclocking, correct?

You need to ensure the heatsink is sitting squarely on the cpu and not riding up on the stepped socket and nothing is blocking the area around the heatsink that would interfere with airflow.

AMD XP processors max on die temp is 85 or 90C depending on the processor. 60C is way too high for an idle temp. Proper cooling requires good thermal transfer from the cpu to the heatsink as well as airflow through the case to bring fresh air in and carry the heat out.

Here's a link to AMD's cooling guide page 16 showing good chassis airflow.

Problem solved. The guy who installed it said he got too cute with the thin layer and didnt put enough. I don't blame him though, he tried to get it perfect but in turn messed up a tad. Oh well, I'm running 47 C while playing a game now and with my case siding on. Guess it did the trick just right.

Most people think this, but accually this is not the case. If you read on most heatsinks, they are made to have the fan suck air through. Take Alpha for instance, They have a small aluminum shroud covering the heatsink, then the fan sits on top sucking the air through. This gives maximum cooling to the lower fins. Its up to you depending the enviornment.



Here is a quote from alpha:

Which type of fan heat sink is better, "expulsion type" or "induction type"?
According to our tests, the induction type showed better results the the expulsion type. This is because we used an intake cover to draw air through the lower part of the heat sink for more heat dissipation from the lower part of the fins. However, if some other heat source is located near the heat sink, heated air would come into the heat sink and affect the thermal performance, so the choice must be made depending on the environment.



Take a looksee

I get 55 C after playing a game now (warcraft 3) is this okay? I noticed my temps are better minus the side panel. Going back to base one

thats aite
ive had the side of my case off almsot 2yrs lol
