Overheating

I'm running Windows XP (but soon upgrading to Vista), I have a 500W Enermaz Liberty ELT500AWT ATX12V PSU and I am about to buy either an XFX GeForce 7900GS or a Foxconn GeForce 7950GT I will not be overclocking either, do I have to worry about my machine overheating with either option. I know nothing about installing case fans or heatsinks so I'd really don't want to deal with them. I'm just worried that after installing the GPU it will overheat the system.

It's an HP Pavilion a1650y
2GB's of RAM
1 Hard Drive (80 gigs)
1 DVD-RW drive
a PCI card
And I think one fan (2 if you count the one on the PSU)

I suggest...

In reply to: I've got

You have a basic OEM type system, so I suggest if you can install one, a "buss type" fan to better exhaust the system case. Make sure the wiring&harnesses are routed to allow better airflow throughout the case. When you get or before you get the new gpu, check its requirements. You can visit their support website and see what they suggest for power demands. Many new gpu video cards want at least 350W, but that's a stable 350W PSU. In other words a cheap PSU may have a decal with ???Watts, but is that stable and for how long once you get real power demands on a "constant basis". Your current 500W PSU suggests it can take it, but in the real world, I usually use this rule of thumb, whatever the wattage, only 75% can be depended upon, that would be cutting it close with your current PSU. I would try though, but if you get any weird problems, then get a newer PSU of a higher wattage rating and of course, a namebrand as well.

Actually

In reply to: I suggest...

It is 80% efficient (is that were you're getting the 75% from?)Also because of the PSU would you recommend the 7900 GS over the 7950 GT? And lastly I have no idea how to do any of the case fan thing you were talking about, can you recommend a website that I can get information on choosing the right one and installing it? Thanks.

The legwork

In reply to: Actually

I said, "my rule of thumb is 75%" regardless of the 80% you got stated somewhere. My rule is more conservative but applies quite well with about any PSU out there and be safe. I didn't offer what gpu to get, but did state you visit thier support website and get the "facts" that way you can determine what it *really needs*, no guesswork, its stated by them via the specs. A buss fan is any fan that works directly from a slot, as the slots are also busses or the whole slot segment is the buss. Find or google for vendors of fans and/or cooling devices, they'll carry many different cooling options. I made some suggestions, I hope you're willing to carry out the homework, as cooling gets into many phases of options.

fans or fan mounts are located. They're typically 80mm with some 120mm and they're not expensive...usually the better fans are a little more expensive, quieter and have ball bearings...some have speed control too ...temp or dial your own.

That would be great but I don't have an empty PCI slot. Is there a program anyone can recommend to monitor the temperature of the PC.

One more question

In reply to: Overheating

Since I've installed my PSU (2 days ago) i get a static shock when I touch the metal casing of the fan (not the fan on the PSU but the one under it) should I worry about this, does this mean I did something wrong when installing it. Once I touch the case it doesn't shock me the next time I touch it only if I touch it later.

Well everything should be grounded

In reply to: One more question

If it isn't, that statics going to find its way some place less delicate. See if you can ground it.

Collapse -
Yeah

In reply to: Well everything should be grounded

I think it fixed itself it hasn't done it yet today so hopefully every thing's good.
I was thinking of getting something like this
http://www.newegg.com/Product/Product.asp?Item=N82E16835185027
Would this be difficult to install, and exactly were does it get installed. If this is not a good option (the price seems a little high) the can you recommend a different one.

Thats a heatsink

In reply to: Yeah

Thats why its so expensive. Heatsinks are for CPUs. Usually when you buy these motherboards and CPUs? Like the website at tiger direct they have "may we recommend" section, so you know you're getting the right one.

For PSU (power supply unit) cooling, which is what I thought you were talking about, you can open up the case of the PSU and replace the individual fans for about 1.50.

You need a heatsink fan. You can't run your new processor without one or you'll ruin it. But you need one that fits. Maybe go to the tigerdirect website? And type in your speed and make of your CPU like you're going to buy one. And then see what the recommended heatsink is.

Also remember whenever you do work on your computer. Even just putting in a new card. You have to have all that static discharge discharged. Touching your metal case will ground you. And your computer holds a reserve charge that, if you open up the case (after its unplugged) you should first hold in your power button for 3 seconds to discharge the reserve. Static electricity also disperses if you have a damp rag around. If you tough a damp rag the electricity will cancel itself out. Don't get the inside of your computer wet though.

The motherboard and PSU, they all use the metal case for grounding. If theres a static discharge somewhere you should make sure everything is properly screwed to the case so it can ground.

I hope everything works out for you. Just take your time and make sure everythings done right and you'll have yourself a great system.

needed. I don't know what fan I currently have (I will check when I open the case to install the GPU.) So I really don't know what would be good to replace it in.

Also while running games on my current card (GeForce 7350 LE ) the temperature is around 53C, On a website I saw that 70C is dangerous. So with my new card (Foxconn GeForce 7950GT which comes OC) do you think it will be raised more than 20C if I do not install a fan.

with a noisey fan in it and I replaced it by just buying the fan at radio shack for about 1.50.

There's other options too you know. But 50 some degrees doesn't seem that hot compared to others. One card I read about operates at 64. Thats why some of those new gaming systems got liquid cooling systems.

Ok I got and installed my GeForce 7950 GT

In reply to: Thanks for the recommendations.

and it is amazing! I also download speedfan to monitor temperatures. It lists four temperatures and they idol at Temp1:30C Temp2:41C Temp3:-128C and HD0:26C. When playing games they have maxed out at Temp1:34C Temp2:53C I don't remember the other two but they didn't jump much. Is this a good range for a Pentium 4 3.06ghz?

Second question I tries to download drivers from Nvidia's website (at this link http://www.nvidia.com/object/winxp_2k_mobile_84.63.html) and when I tried to install them it said I have no hardware to support these drivers, now keep in mind I am having no problems with the current drivers I just though I should get the current ones. Is it worth trying to get the new drivers in this situation?

About that no hardware message.

about the temperatures

In reply to: Ok I got and installed my GeForce 7950 GT

If Temp1 is system and Temp2 is CPU, then those temps look good for a P4, especially for a Prescott core.

Temp 1 actually rose to 36C earlier, is that still okay. What temperatures should I be worried about.

still good temps

In reply to: .

System temp is lower than CPU temp. Worry about CPU temp first--for that CPU, good cooling means it should be below about 60

I haven't really tried it under a full load

In reply to: still good temps

I've only played Knights of the Old Republic 2 with everything maxed out. I will try Half-Life 2 later. If I find it gets over 60C what kind of fan do I need to install.
