PITA fans?

[SteamWake]

Not to long ago I pulled the heatsink/fan off my cpu to clean.

Not to hard to remove, had 4 tabs that quarter turned and pulled up to release.

The trouble cam when I went to replace it. If it wasent sitting just exactly so on the cpu the machine would cut off in a matter of seconds. Took me quite a while checking that everything was plugged in the right place etc. before I realized it was that the heatsink was not seated properly.

So just a word of warning.

LGA775 socket? Always had trouble getting that sink in place as well.

And yeah, the front intake fan in my case is a real pain too. At some point I removed it to put it back in with vibration dampening mounts... took me a hour to get the cursed thing back in place.

The airflow in my case is going one way - just back to front. I put an 80mm fan in front because it is way too hard to put another 120mm in. The front grill has holes for an 80mm or 120mm fan. Before I switched the front fan around all the fans were pointed inwards. My case has a 120mm fan on back, an 80mm fan on the side covering the video card, and now an 80mm in front (expelling the air). It really is no trouble having air coming out the front. I agree that a 120mm fan would be better, but I wasn't going to fight with another one. So far all my temps are normal if not even cooler.

Hmm realy? as that is odd..

Is the case set up for it? what about the power supply?

If you got more fans in the back you should run it the other way, particularly if you got a video card and/or power supply venting out the back, otherwise its just going to suck the expelled hot air from those 2 things back in the case.

Usually the cooler air is found in the front of the machine due to how we tend to keep the back close to walls or corners, and how most computer desks are designed.

Here is a site that reviewed the case I have back in 2005. I didn't read the review but the pictures on the review look like mine except my case is all red instead of black and red. I didn't use the PSU that came with it. I have a Fortron Blue Storm 500w with a 120mm fan.

Here's a pic showing my system temps:



Here's one showing my video card temps:



Everything seems to be ok.

Some of the fan positions are a PITA for sure. It took me awhile to build but I have a 120mm fan at the rear and underneath, these are high rev fans (around 4000rpm), both have external filters (the same as used with airconditioners), I also have top and front fans that expel the hot clean filtered air, works well!

Hmm well for that case design you technically have all the fans blowing the wrong direction. What will happen if you have any good kind of video card (especially if you have 2 or more of them) is they will expel their hot air out the back, it will rise up, and get back in by the fan above and blown across your cpu (and some of the hot air expelled from the psu will get sucked back in due to proximity). Also if you have a horizontally mounted cpu cooling fan then you may have the 2 fans fighting each other.

The temperatures you posted prove nothing I'm afraid, your system was idling at the time you took them and thus meaningless. Plus they may be erroneous if the sensors are not properly installed, and it may not indicate any hot spots on the board anyhow. You would need to run your system 100% maxed out for about 10-15 minutes to know if there are problems or not.

Also another issue is that the air screens are on the front, so any dust getting in the system will get stuck on the inside of the screen and will eventually clog up.

Anyhow I stand by my original recommendation of having the air flow front to back.
