CPU Temps and airflow

ABOU · 11-03-2003, 04:06 PM

u think ur pc's are runnin hot

i have just got my 2800 goin and it runns at 60/65 degrees c this is with a coolmaster 3000+ (supposedly) fan

i have not yet got my 2 case fans installed but still this seems overly hot any ideas ???

(i have been told 2800's run hot)

ABOU · 11-03-2003, 06:27 PM

ok i seem to be able to get the temp down to 57 degrees idle do you think i shud maybe go for a cooler master jet 7

i have a link do you think this would improve the tempreture

have you also thought about getting fresh air into the case?

this is how i managed to get my running temp down to 36 to 42max load.. thats what im always running at now, i have 2 fans running air out and one fan running air in.. it keeps the circulation going.. so before you go spending money on more expensive fans, id suggest taking a look at how well the air is circulating.

My method of checking the airflow was to plug the pc in outside in the garden propped up on a table and then to turn it on, let it run for a few minutes and blow some fresh cigarette smoke in through the air intake... it filled up the case nicely and showed me where the smoke was settling (i can see inside cos of my window mod, just incase your wondering) and where it was being sucked straight out.. thats how i know wher the hotspots in my case are. i have 2, on under the hard disk tray and one under the pci card slots.. luckily the air blowing into the case blows over the graphics card and keeps it cool aswell as the cpu..

if your going to try this, i seriously suggest you do this outside if your house is a non smoking environment and let your pc run for a good 10 minutes to get the smell out of your components!

well i also have a mod case and i have not yet got me case fans runing but there are 2 spaces in the back of the case

as for intake out take do you have to set the fans to in/out ??

im gettin 2 case fans so im sure that will bring the temp down but by how much i wonder ??

Kungfucious · 11-04-2003, 04:53 AM

well yes and no in a way, the only setting you need to do is a physical adjustment of the fan, if its currently blowing air out of the box, flip it around so its blowing in.. simple as that,

also, try and position them so that you have some kind of crosswind going, that way your sure to get good air in all corners.

Air in from the front and air out from the back works well, but sometimes even this doesnt work though, for instance, if you have a jungle of wires in your box, it causes disruption to airflow and actually increases temps because it cant suck the hot air out fast enough. You need to strike a comprimise between good air and good circulation.

Also something i just remembered, make sure to fit a filter on the intake as LOTS of dust will go in, as i found out after 2 weeks of running the intake and wondering what all that fur was on my Radeon!

ABOU · 11-04-2003, 01:28 PM

i c wot u mean now well there are 2 case fan bays in my case at the back one above the other so i would put the inflow on the botom and the out at the top as it will collect most hot air as heat rises

is considering puting a blowhole in the top of the case but not right now i will keep you updated when i get my case fans

ABOU · 11-04-2003, 04:51 PM

ok i have installed 2 coolermaster case fans on intake and one out take as i post this my cpu is still running very hot at 56 degrees but it may be different i will test it as the night goes on but i may need a new cpu fan

ABOU · 11-04-2003, 05:18 PM

ok here is what im gettin not to sure on how or if the fan speed can be ajusted manualy ne knowlage ??

igalan · 11-05-2003, 11:41 AM

To keep a good airflow you should place one fan blowing air out of the case, below the PSU. If possible use a PSU with two fans. Also you can place a fan in the front of the case, at the lower end there is a place for an in-take.
What is the exact model of the CoolerMaster that you use for the CPU?

ABOU · 11-05-2003, 11:55 AM

i have had a look and the only other place to hous a fan is in the middle of my window :S

would this provide a better air flow ??

as for the make of the coolermaster it is just a basic fan nad heatsink up to xp 3000+ im not sure on anymore than that

im still not sure hwo to up the rpm of my fans any help ??

igalan · 11-05-2003, 12:14 PM

There is now way to change the rpm. You just plug to the correct header and it will run at a fixed speed. It is possible to add a regulator to manually adjust rpm, but that's not your case, I guess. Also ASUS A7N8X is able to throttle CPU fan based on to CPU temp. But I don't know if Gigabyte can do this (you have a Gigabyte mobo, haven't you?

ABOU · 11-05-2003, 01:35 PM

i have a gigabyte board well im hoping that repositionig my case fans will improve air flow

does anyone know what temp an xp 2800+ should run at typicaly ?? this would help alot

igalan · 11-06-2003, 04:44 AM

The AMD XP 2800+ should run at 1,650V core, and I noticed that you're running it a 1,720v! This overheats the CPU, and if you're not overclocking, there is no reason to up the VCore.

LPDad · 11-06-2003, 05:54 AM

Mine runs at 37-39 C (Idle) and 46 C (full load) with ambient air = 27 C.

Using the Best Heatsink --> Thermalright SLK-800.
Nice big QUIET 80 mm fan on it. I will NEVER go back to a HSF that uses those itty-bitty 60mm Screamers running at 5,000 rpm.

Ask Berks about those....He originally had a HSF like the one you describe..but I converted him...and now he is very happy.
