PC was working fine until i changed to a new media case. Now the cpu temp is getting up to 65 on occassions. The previous tower case did have some sort of vent that overhung the cpu fan, however, even with the new case lid off, the temp is still rocketing on occassions (seems to creep up over the course of an hr or so). I have re-fixed the cpu fan and it doesnt seem to have made any improvement. Anyone got any advice? maybe a new heatsink? however with it previously working, got me a lil baffled. The only other reason i can think off is the case fans. The previous case had two 120mmm fans, one acting as an exhaust, the other pulling the air in, and the temp was usually mid 20's. Now its sitting at 30 to 40. There is space for two 80mm fans directly behind the cpu, one 120mm fan directly to the side of the cpu, and one 120mm fan on the opposite side. How should they be set up? ie, what ones should be pullin the air in, and what should act as the exhaust?? I have 4 80mm fans working away, 3 putting the air in, with the one to the right of the cpu pulling it out. Any help, greatly appreciated
65°C is pretty high temp for a cpu. The cooling you say you have at the moment is reasonable i'd say, So theres gotta be another reason for it. Could be that the Thermal paste between the cpu and heatsink has gotten to the point that it needs replacing, as there might not be alot of contact between them. So its definately worth giving that a try first. Arctic silver 5 is the most popular of pastes as it has a high metal content which increases conductivity. Obviously If you have space for more fans its a good idea to add them especially the large 120mm fans which blow alot of air in&out with reduced noise vs the 80mm fans. Regarding fan placement its usually front of pc as intake of air flow & side of case intake, rear of case as extract and top of case also as extract.
Alright well a good configuration for your case fans is to have the ones in front sucking in air, the fans in back pushing air out the back, and any fans on the side/top pushing air out of the case.
Appreciate the help, ill check the heatsink and most likely get some of the stuff mentioned for it. I wasnt very clear before with the fan layout, but theres no space at the front of the case. Its a media case, the psu is locaed at the front with a grill directly above. The cpu is located to the rear right, and have two fans directly behind it, and one directly to the side. The other fan space is on the opposite side, but due to the tight fit of the machine, the graphic card along with the cables from the psu, are pretty much preventing any real direct air flow from side to side. Should having two fans behind pullng the air in, and the one to the right acting as an exhaust be good enough? They are all within a hands distance of each other if yo can picture it. I was thinking of adding a grill on top of the case for the cpu, but with it goin in a unit (DVD type), there wouldnt be much space to make the diffeence i doubt. Thanks again

I see what you mean there being quite compact. I take it your last case was an upright tower case? The 2 fans at the rear should be extracting the air flow out and the side for instaking, if you can add another fan the opposite side also intaking air it would be a good idea. Also try to get rid of any protruding wires near the fans using cable ties.
Yeah last case was a tower, and never had any problems even when cpu at 100%....kinda regret switching, but has to be done for the new house. Appreciate the response though, iv got the fans the opposite way at the min, intake from the back and exhaust on one side, ill try switching them and also replace the 80mm on the sides with 120mm. Kinda hoping doin that, re-newing the thermal paste will hopefully solve the problem....and cable ties off course, havent really tidied the case up yet as i wanted to make sure it was working fine before tidying it all up. Cheers
Well a good way to maximize airflow, like jazbebies said, is to hide your cables. If you have a mess of cables in your case you are severly hampering your airflow. Try to take every cable that is in your case and route it along the bottom side of your case/motherboard. This will increase airflow to all the other parts.
Two 120mm fans, heatsink new paste and cables partially tidied up, powered on and cpu sitting at 29 with system temp at 21.......way better than previously. Im not going to get to excited yet as there has been no load on the cpu, however it is clear the suggestions have certainly improved the temp inside, so many thanks for the advice. Can anyone suggest a programme that will really test the cpu and monitor the temp over a few hrs for instance? Be quite keen to see wat the temp would be like after some work. Thanks Again
Just tried a programme called sis software sandra, which carries out a few tests on the cpu etc and max temp it got to was 52 for a second, while at 100% cpu useage, which i think is pretty good....topic can now be ended and thanks again
Congrats on the cool running system. Just to throw this in, the program SpeedFan is a nifty utility that reports the temps from all over the motherboard. Also if configured properly and if the fans support it, SpeedFan can automatically increase the fan speed when the load on the cpu increases and decrease fan speed when the cpu isn't being used.
