Temp difference between case temp and CPU temp

germanjulian · May 3, 2004, 11:53 PM

Please only post in this thread when your CPU is under 100% load and has been under 100% load for at least 1 hour.

difference is: 17C

Please post and vote your temp difference between your case temp and your CPU temp:

ie: case temp is 20C and CPU temp is 40C = +20 temp difference

please say if your using watercooling or have a duct or no case!
Extreme cooling people your not allowed to vote! please

would be cool if you would also give your setup: ie what fans and what speed. I am just curious.d[/B]

My setup. All vantec stealth fans and SLK947U heatsink with 80cm stealth fan. 2 intake fans and 1 out. fans at full speed but can be controlled to run even slower (ie nearly off )

difference is: 17C

ohhhh this forum has no polls..... well just post then.

Judas · May 4, 2004, 12:25 AM

er... is there a negative value? my mobo temp is nearly 10*C higher then my cpu temp.... yeah.. kinda weird hey? 12 80mm generic/and leded can fans.... retail/stock cooling...

Fantasma · May 4, 2004, 12:59 AM

LOL, my difference is about 20C, after pure gaming, I get 40C the case and 60C the cpu

@/2ct!< · May 4, 2004, 01:06 AM

CPU temps are such a pain to read accurately that it is quite difficult to see differences between ambient.

Vampyromaniac · May 5, 2004, 08:56 AM

Last time I checked, difference was 16ÂºC
1 case fan: 120mm ????rpm blowing out
CPU fan: 80mm ~4200rpm blowing up, heatsink is Alpha PAL8045
power: ??mm ~2500rpm blowing out
case: Antec Sonata, no mods, door is on
fans are normal speed/no controller

hope that helps

In idle my CPU temp is 45C according to ABIT EQ, after playing FarCry, CM04, NFSU my CPU temp rises to 52-55C.
Ihave a Antec 1000AMG Plus View case with 2 80 mm fans blowing out the hot air, 1 80 mm Fan in front of my hd;s and 2 in my PSU.

The_Neon_Cowboy · May 5, 2004, 09:04 AM

Going by my nforce 2 temp and my cpu temp the diff is only about 3c

2500+ 1.68ghz oc to 2.09 GHZ (2800+)

MB temp 31C
cpu temp 34C

I'm useing an finely lapped slk-800U with a 43 cfm (32 db) 80 mm fan
case wise iu'm useing a mid tower with 80 cfm in 80 cfm out
north bridge cooler has been replaced themaltake crystal orb
my mosfets have been heatsinked
I have added a heatsink on my south bridge

room temp abt 74F

BTW thats not exteme cooling that every day stuff for my systems
just becouse most people under cool doesn't mean i'm over cooling

also note the noise level is quite low long as i have my case sides on

Idle my system is:
Mobo 31 C

After several hours of UT2K4 - SWG:
Mobo 32 C
CPU 45 C

Sofar all is running on stock cooling..

~~BMG_Cya=-~~ · May 16, 2004, 10:33 PM

These are averages as I have done this many a time with different
benchmarks, games, graphics cards etc.

AMD ATHLON XP 2800+ @ 2.15 ghz = 30-41C
(Artic Silver Thermal compound...AMD retail box aluminum HS...80mm Vantec Tornado (roughly 90cfm)

The above CPU temps vary according to game, (Painkiller raises my CPU temps the highest...for ex.)...
benchmark, (mostly Aquamark03...ATI Tool...Radclocker, rthdribl, Sandra 2004 Burn-ins etc.
Don't use 3DMark03 anymore, as I believe it has become basically a joke.)

Graphics Cards: Gigabyte Radeon 9800 Pro 128
BBATI Radeon 9800XT 256

Full Tower aluminum case
9 x 80mm case fans ranging anywhere from 3 more Tornadoes....PC Toys Tornado (90+cfm)...to
Antecs 30-45 cfm

Also...Kingwin 450 watt PSU with 3-fan intake and/or exhaust 80mm (Turbo setting 24/7)

Case temps usually 5-9 degrees celsius cooler than CPU

The answer for my system is 7c.

Details:

To obtain 100% full CPU load I ran Celestia,
All testing done with Cool-'n'-Quite enabled.
System load includes Nokia 445PRO 21' professional monitor (85W measured).
System case Thermaltake V1000A includes 7 fans - Power-Supply includes 2 fans - ATI card includes 1 fan - CPU includes 1 fan = Total system fans (7+2+1+1) = 11 system fans.

Idle - Room: 23.3c - Case: 26.0c - MB: 41c - CPU: 37c - System load: 300W
Full - Room: 23.3c - Case: 26.1c - MB: 43c - CPU: 50c - System load: 360W

Case load effect: .1c
MB load effect: 2c
CPU load effect: 13c

Case/CPU load difference: Idle: -4c Load: 7c

Time required for CPU to reach idle temps after test ~10 minutes.
