Tbird 1ghz temps 61C what can I do? - Updated

[Rottnweim]

Update:

I cut 2 "breather" holes (3 1/2&quot in the back of the desk behind the exhaust fans of both the power supply and rear fan. I can feel the airflow behind the desk....temps now down to 53C under load and and about 50C at idle.


BUT it is a lot cooler here today than the last few days...


BTW - I tried to mark holes for the extra case fan I got just below the one that fits into the 'factory' location (in the upper rear) and I found that it wont fit! I guess I will have to put this one on the side of the case.... or maybe move the current one up a bit and squeeze this one in there. I'd better get some dremel tips!





Built this system a few months ago...never really checked temps at first.
Got MBM5 and temps used to be around 45C. I have not made any changes since then. I have an Enlight 7237 case with the stock fan in front, and I added one in the rear. Yesterday I got a new CPU fan from my local computer store (the Globalwin FOB38) and the kid said 'this one will bring those temps down'. Well, it hasn't changed them a bit. The old fan was a cooler master. I removed the thermal pad from the HS and cleaned well with goof-off and applied a thin amount of "tech spray heat sink compund" (rat shack only thing in stock) on the cpu.

Right now im at 54c at idle.

System specs:

Asus A7v133
AMD 1Ghz T-bird not OC'd
256Mb pc133 infineon ram
Ati All in wonder radeon AGP
Creative Labs SBLive! PCI3
Kingston NIC KNE111TX PCI4
Maxtor 7200RPM 10GB Ata66 primary master
POS cdrom 52x primary slave
fujitsu 4mb secondary master
Maxtor 5200rpm 6.7GB secondary slave
Enlight 7237 case stock fan in front another fan in rear below PS
300 watt PS
Windows 2000 Professional
I think my bios is rev 1005c (not the newest)

So what do you guys recommed I do? I'm wondering if I got a new 60GB ata100 7200rpm drive and got rid of those smaller drives if that will bring down my temps. I have another case fan, but I gotta pop in a hole for it, whats the best spot?

Thanks for all help.

Those are fairly normal temps for a7v class MB's. NO matter what heatsink you change too, they won't change drastically. THis is becaue your temp readings are almost solely dependant on hte motherbaord.

but a few questions:

What is your room temp and case temps like?

[Lithium381]

so you only replaced the fan? not the actual heatsink? try that....um, room temps have lots to do with it, and do you have good airflow in your case?

 

[Rottnweim]

My room temps here in hot california are about 100F (38C) and I dont know case temp.
With the side of the case open (normally its closed) I can feel good cool airflow in from the front.
I tucked the IDE cables to provide better fresh air flow.
I would imagine exhaust is ok, though maybe since its in a desk that i should cut a hole in the desk directly behind the PS and rear fan to get that hot air out of the desk computer section.

And yes; I changed BOTH the heatsink and fan (the FOB38 is at least 30% larger than the coolermaster) and the fob is considerably nosier too.

 

[mrEvil]

Rottnweim, your room temperature is 100F? Are you perspiring profusely while at the PC? Just want to make sure that we're talking about the room temp where the computer is at, not outside.

Correct me if I am wrong, but doesn't the 7237 have the separate side doors? First, try opening the side door where you stick your cards in. Now, tell us what your temps are at an idle state + full load.
My 1.2Ghz will be only 1C(28C vs 27C) over my room temp when idle when I have my case off. Put my case on and everything changes. I'm in the process of saving up for a new case, but until that point I'm running it without the cover. I only have a 23CFM fan(upgrading this also) on my 1.2Ghz and with my case off, the CPU barely hits 50C, and it's not frequently that it does (Prime + UT will do it).
To throw added heat into my equation, I also have (3) 7200 RPM Maxtor 30GB drives + (1) 5400 RPM Maxtor 40GB drive. Add in my 16x Teac CDRW and Toshiba DVD, GF2 MX, Hercules Game Theater + NIC.

You're right on making sure you have a port in the desk for the exhaust air to escape from. I think you could get it a little lower. 54C at an idle state seems sort of high to me.

Mr-EVil,

Are you familiar with how the a7v reads temps? If not, you can't even remotely compare your temps to his. A7V/A7V133s idle higher than other boards due to bios problems. THey read higher overall due to how Asus compensates the socket-thermsitor reading.



Mike

 

[Rottnweim]

Well duh, I guess 100 IS a little high for my room temp! I just peeped the digital thermostat and it reads 92F...so I guess Im off by 10 degrees or so...my bad! (although my wife thinks it's like 85 in here...i think she is crazy though.)

Yes the 7237 has removable doors....but since the fob38 is MUCH louder than my previous fan, I havent run her with the side open...ill try that.

Before purchasing a new heatsink/fan I did remove the cover for a day or so and the temps were not improved...61C at load (I think it could have been sucking in the hot air (from the side) that was being exhausted from the back of the pc)



mikewarrior2:

I HAVE read that the A7V does inaccurately display the temps, but this just seems too hot for a non-overclocker with a pretty large fan/heatsink...are you saying that a bios update may help my temp problems?

 

[Mikewarrior2]

For a 38C room temp, it isn't too high of a CPU temp for an A7V.

On the subject of accuracy, no SOCket-a board is accurate. Its all guess work. It just happpens that asus has implemented a compensation that results in "hotter temps". That doesn't mean it is more inaccurae than other boards. If anything, the higher compensation is a closer representation of actual core temps.

[SpaceC0wb0y]

I have a 1.2ghz t-bird with a abit kt7a mobo in the same enlight case with the added fan in the back. My cpu temp is running at about 47 C idle. I would like to get it down without replacing my COOLER MASTER EP5-6I11 heatsink.

Does this abit board have accurate temp readings?

I was thinking about putting a fan in a 5.25 drive bay, would that help at all?

 

[Glow]

try an air conditioner instead of computer fans, it will work wonders on your BO.

 

[PowerMac4Ever]

MikeWarrior, are there any good software apps for measuring temps? Any app you recommend?

Motherboard monitor.

mike

but ur explanation doesn't explain the fact that he routinely got temps in the 45c range, then he changes hsf to a better one and gets 54 to 61c. u can't explain that away by saying it's the way his board reads it.

rottnweim, i'd get some ASII man. that spray, i don't know, one nice thing is u know u didn't put on too much, but ??.

also, check to see that the bottom of the FOP is flat. if not, u may have to lap it.

finally, u didn't mention a shim, hope ur not using one, but a lotta times, increases in temps like that indicate a shim being used that was bent, dented, or just plain didn't fit.

good luck man.

Mike - thanks for slamming me while I'm attempting to help him out. You're right...haven't owned an ASUS board since the LX days. Guess I will not offer any suggestions next time....guess going from 45C to 54C is nothing to worry about.

Space Cowboy - have you stuck a couple of Delta's (80x's) in that 7237? That should push some air flow through there. I like the design, but cannot use mine with my raid setup as there are not enough bays for me. Beyond that, if you want to disperse more heat, you probably need more CFM from your fan on your heatsink if you do not want to switch heatsinks. Otherwise, either a bigger or more heat conductive heatsink would be the next choice.

The only other suggestions I could have would be the ASII, which has been noted, and possibly an Enermax power supply. They make some nice, dual-fan power supplies that are pretty quite and are some of the best home marketed PS's that I've seen or used.

 

[sanaka]

I was just swithing HSF's while getting a real handle on using thermal compound correctly (just the cheap white stuff, ASII i think is not so stiff). Took me 4 or 5 tries to get a nice THIN layer that also covered the WHOLE core. Maybe I'm just a klutz but seems there's a finesse involved w/ that.

Temp readings w/ same (lapped) HSF varied 10-12c between good and not-so-good application of grease!!!

 

[Mikewarrior2]

Umm... Mr Evil,

That was not a slam.. It was a clarification so that you can't compare your temps to his. Different mb, different temps. Period.


PlatinumGold,

He hasn't checked temps since a long time ago. Since summer has arrived, 9C increases in room temp are common, especially considering his 100F room temp.

I highly doubt his room temp was 100F a few months ago.
