CPU Temp too hot !

[MacUK]

I,ve built a new pc and my proccessor runs at 60C temp which I,m told is too hot. I,ve already got a big heatsink/fan on processor and two fans in the case (one suckin one blowin) So how can I make this proccessor run cooler than it already does ???


AMD 1.4 TBird
Gigabyte GA-7VTX
246meg
40 gig HD
MidiTower (350 watt)
GForce II Mx400

I'm wondering if maybe having both fans blowing the same way would help.... I have an athlon 1.4, 350 watt power supply, cpufan/heatsink, 7200rpm hard drive, and 1 fan on the power supply, blowing out of the case. No case fan, the mid tower is in a desk with a door in front of it, and I have the cpu running at 100% 24/7

The temp rarely goes over 56, though for the first couple of weeks after setting up the system it ran at about 61 or so. Anyone know how hot is too hot?

looked up some info, a post from someone who contacted AMD. and they werent worried about it being in the 70's. A few pages quote amd as saying the max die temp is 90-95.

Dump it and get a P4. You'll then be able to
take advantage of Tmpgenc's new abilities.

get a good heatsink i suggest
which u can get at http://www.theoverclockerzstore.com
don't get a p4 lol get a amd hammer
2.0 gig chip dogs the p4 in everything
has a similar thermal protection that the p4 has

[kr0n0s]

you can always port the front and attach an air conditioner
that should keep the temps below 20 degrees on any cpu.. sure did for my duron

Hi,

as a react on the P4 remark. A P4 can work fine till about 70-75 degrees, and is normally working about 45 degrees. An AMD Athlon works fine till about 90-95 degrees, and is normally working with a temperature of 50 degrees. (1.4 and hihgher) There is no advantage for SSE, as the new Athlons (MP and XP) also support SSE.

To answer the question about the temperature:
Not only the heatsink for the CPU is important, but also the temperature in the case. If that is too high, then there is no way do drop the temperature of the CPU with a bigger heatsink.
You'll need 1 or 2 fans blowing air inside the case from the frontside. Then you'll need 1 or 2 fans blowing air outside the case at the back. This way you'll get a colder airstream passing by your heatsink, and that way the CPU will be cooler.
I have done it this way, and the temperature of the case is normally 29-30 degrees, my AMD Athlon 1.4 Gigaherz has an average temperature of 50-51 degrees.

My friend had the same heat problems with the AMD, he invested in a Thermaltake Dragon Orb 3 heatsink/fan and was happy with it for awhile:

...but then he got an P4 and never worried about heat again...

[xzarkad]

.....same goes for the Athlon Xp 1800+. It will not become any hotter than a P4..............

xzarkad,

P4 has SSE2. No Athlon CPU has this. TMPGEnc 2.0 is now optimised for SSE2 as well.

septor, the hammer line of CPUs don't exist yet. You can't tell someone to get something that isn't on the market.

Regards.

Vitualis is right - no extant AMD CPUs make use of SSE2 instructions. TMPGEnc is, in fact, the only program that I know of that makes use of this instruction set. A lot of posters here use TMPGEnc quite frequently, so its SSE2 support might make P4s a bit more attractive to this forum's members.

The topic, though, is not AMD vs Intel, but CPU temperature. While 60 C does sound hot to me, perhaps someone can provide documentation showing that that temperature is indeed dangerously hot. My CPUs run at about 50 C when under a full load for an extended period of time. While 50 C sounds hot to me, my system is always completely stable. Just because a certain temperature sounds too hot doesn't mean that it is. Check up on it.

Just for kicks, remove the case cover and run for a while and repost the CPU temperature. I once had a problem where my computer was running too hot and my computer would just shut down after a while. This was right after installing 128MB RAM. When I opened it up to look around I noticed that this errant behavior had stopped and eventually discovered by trail and error that it was the case temp (although I can't measure that easily so I just went by CPU temp). My case had no fans (it's an old AT style case that my original 486 came in). I installed a HD fan in one of the front bays and one of those card fans in the back:
This is the Hard Drive Fan:

And here is the card fan (you can put this in any empty slot):

And after that I can put the case back on and it works just fine now! And the HD fan sucks and the case fan blows.

These temps are from AMD's Technical Documentation

This specifically is from page 20 and 25 of the pdf at http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/23794.pdf

For AMD Athlon Processors (Socket A, NOT slotted) the maximum die temperature is: 90c for under 1100mHz and 95c for 1100mHz and higher.

For AMD Duron Processors (Socket A, NOT slotted) the maximum die temperature is 90c.

For all AMD slot-A processors the maximum die temperature is 70c.

Four important things to look at are: Heatsink, Fan cfm, thermal interface, and case temp.

I had a similar heat issue on my 1.33 . I purchased a better heatsink and fan and the temps dropped quite a bit, but still not as much as others I'd talked to. I then tried some atctic silver thermal compound and the temp dropped even more. Now I run full load at ~49 C.
