Vista - Can a PSU cause heat problems?

I have been having alot of problems with a stock gateway lx 6810-01

Problem is the cores are running at like 60c and I know thats above normal.

My question is, can a stock PSU have anything to do with the cores running too hot?

only if the cpu fan is not getting enough power from the psu.

What would be considered the CPU fan? We bought a new heat sink thats huge and says it runs around 2200 rpm's at max with a little knob you turn, but it runs at 900 rpm's at max.

So, PSU issue? Or heat sink issue?

Thermaltake - 120mm CPU Cooling Fan - CL-P0401

As you can see, the fan is built into the heat sink. The only other fans I see in the computer are 1 on the GPU and 1 on the PSU.

The only thing I can think off is that the PSU is super cheesy and not capable of handling the mobo + other hardware and it is suffocating itself.

That or your case is not well ventilated and/or you need to add a couple of fans for more airflow

Third, you can get into the BIOS and manually adjust your fans to 100% so they are blowing at max all the time, it will get noisier but it will cool down your temps.

Last thing I can say is perhaps you used to much, to little or no compound at all when you installed the heatsink.

And how would one go about manually changing all of my fan speeds? I'm looking in bios on that gateway and I see no such option.. The only relative options are Smart fan with an option to enable or disable and quiet startup.

I don't see anything else fan related.

what is the model / power rating on your psu.

also download a program called speedfan and you can really see what the rpms are at

OK, is "Smart Fan" disabled or enabled? If I am not wrong...

Enable = The Bios will dictate how much % speed to let the fan run according to heat temps.

Disable = No matter what, the fans will run at 100%... This is what you want!

did you fit the heatsink / fan correctly? what paste did you use? how much did you use?

have you tried removing it , cleaning and reseating?

fadedrs: We have speed fan already, both the bios and speedfan report the low 900 rpm's. It's a LiteON ps-6401-3 psu at 500w.

AstaLaVista: It was enabled, I disabled it yesterday only to find that the RPM's all ran the same.

Archie123: Yes we mounted it correctly with both the stock one, and the new one.
We used this exact brand of Thermal Compound. Dynex® - Silver Thermal Compound - DX-STC 100

At first we applied too much after watching a ton of vidoes about proper application of thermal compund.. After wards we put a little bead in the the center and set the heat sink on it again and let it spread.
(We used 99% isopropyl alcohol to clean after each application)


I believe too much is bad and too little is bad so we just did the "blob technique" according to a few videos.

(Just read a review on this paste, apparently according to one person it takes about 3 days to reach maximum heat transfer)

maybe return it sounds like the fan is defective

this is the one i have Micro Center - CNPS7500-AlCu LED Universal CPU Cooler never have an issue even after hours of straight game play.

see attached pic. that is after 5 hours of straight game play.
