Hot CPU

[1k memory]

Hi all,

Ive got a AMD 3500+ (2.42GHz) A8V Deluxe mobo with 550w psu. I have the standard CPU fan that came with it, 2 system fans, and fans fitted to my 2 HDD.

Before my cpu sat at around 52C when idling going up to about 55 when working on it. the cpu fan usually ran at 3400rpm and the two system fans aroud 2200 rpm, which im guessing is all normal.

But now my cpu runs at 67C average and the CPU fan at 5400RPM and is a noisy bugger, with the two system fans running at 2500RPM. ive moved now and the room its in now is not that hot really, bit hotter than normal, the back of the tower is about half foot from the wall and the left hand side is about 3inches away from a cuboard and nothing against the other side of the tower.
The question is is it ok to run my system at these temp/speeds?
And why is it so hot, its not as if any of the vents on the back or sides are blocked and i have plenty of fans. my power cables have all got netting around them to help ventulation and i my ide cales are the ones that are in tubes to help circulation as well

Is their anything i i can do to cool it down, i dont wanna putthe tower on my desk as its full of junk as it is and not much space. BTW its an old case so i dunno if new cases help better with ventilation?

Any info will be appreciated

From what you have said I would guess it is your cooler and the flow of air through the system.
What cooler do you have attached to the CPU?

The polished finish of some cases can make a difference in heat dissipation, but airflow is more important, larger towers have more fan locations.

What do you mean by plenty of case fans?

All case fans should extract air from the top of the case, there is no point in having a fan blow air into a case when whatever volume of air is extracted will be drawn in through the vents.

I would recommend a Thermalright XP cooler either 90 or 120 or the biggest that will fit your MB

Fit some 90 or 120 fans to the top of the case and side panel, if you cannot cut the holes get someone to cut them for you, it is simple if you glue the fans together and cut a single rectangular hole, you can always use grilles. Cut half inch wide air intake slots in the bottom of the side panels, you can cover them with wire mesh and spray them if you wish. Connect all the case fans to the 5V rail and even with 6 or more fans you will have an effective air flow you will not hear above the CPU fan. The closer the fans are to the top of the case the better,the more effective the airflow. I used to make 12V/off/5V Baybuses and fit them to drive slot covers for superior fan control. If you use a 120 cooler you could attach a quiet fan such as a Zalman or try one with a high CFM at 5V but you must connect it directly to the PSU and not via a Baybus unless the switch does not hava an 'off' position.

The cooler that i have for the CPU is just the standard heat sink and a normal fan attached to the top.

for the case fans I have two coolermaster fans attached to the back of the case that is extracting the hot air. after feeling the case the top is very hot and the only ventilation holes are little ones towards the front of the tower that i dont think are realy doing much.

had a look inside and their is room for a thermalight cooler i think.

If i was to take a few shots of my Tower would you be able to recomend what would be best for my to do?

Another Q, with makijg holes in the bottom of my side panels would that not draw alot of dust and crap into the system?

You will get dust or crap into your case regardless how many holes you have, I have seen normal case without holes with inch thick dust, but rare.

You are overclocking your CPU, but it doesnt explain why suddently the temp jump so high, take Cougar's advice and get a better CPU fan if you intend to O/C.

If your PSU is getting hot, this could explain why your CPU is getting warmer, the CPU is drawing in more warm air than it should as they are normally sit right next to each other.

Yea ive set it to 10% in the bios but thats one of the standard manufactures options so not as if its excessive. I brought a new psu a few months ago but it was fine at my old place. Think i might get a new CPU fan and make some ventilation in the top for the air to escape as their isn't anywhere for the hot air to go at the moment.

Thanks Duffy/Cougar

turn off pc

remove all dust

remove normal heatsink/fan

clean cpu with cleaner and apply arctic silver 5

buy a arctic freezer pro or simular

if u have ide buy the rounded cables

tie wrap everything so u have more space for air flow

1 x front and 1 x back fans also help for air flow

hope i have helped

In answer to your other question, yes it will draw in dust but no more than from any other part of the case but it will pass through the system with superior airflow, It is hard for dust to settle where it is windy.

A hole in the top of the case will be ok but fit a blowhole fan, a 120 fitted to the 5V rail will be practically silent, but not all fans run at 5V/12V so check, and as I said earlier if it is wired to 5V get one with a decent CFM

The only thing I recommend you do with the stock heatsink and fan when you remove them begins with B

Arctic silver compound is good advice, more good advice is after you carefully clean the CPU mating surface give it a clean with an alcohol solution. do the same to the mating face of the cooler then do not touch the surfaces with your bare fingers, or you may as well use marmite instead of heatsink compound if the mating surfaces have greasy fingerprints on them

arctiv silver compound does nothing at all
its all bull
the only thing that works are the heat sink pads

i would say if your pc cpu is going up in temp and you cleaned the fan
and remove any dust and does the same

its more likely that the cpu is getting to hot and is at fault
because you defaulted the setup in the bios it wont be running at the right speed so it wont heat up as much

go into the bios and watch the temp in the cpu and see if it goes up
anything over 75 to 85 is a no no

when you default it the temp should be around 47 to 50 if that

i have created some some hles at the top and added two fans to extract the hot air and have given the heat sink and fan a good clean out and all seems fine now, genarally around 54 on a warm day, 49 at moment cause its quite cold.
