i5-3350P running extremely hot at all times

Hello, members of the TH community, I recently took the plunge into building a PC for gaming with an i5-3350P. I put it together yesterdayThe build went mostly well, but there was a massive problem when seating the processor heatsink.

Foolishly, I went for the stock Intel heatsink and...yup, people were right, these things are just plain horrendous. One of the four pins simply didn't line up with the holes in my motherboard (an ASrock Z75 Pro3 for the record). Not at all. I foolishly tried to force it in, and the entire pin BENT (as in, the white part that's supposed to go through the hole bent and couldn't go through it anymore), and I simply said "screw" it and only tightened down three of the four pins. Then my mobo accidentally shorted out due to faulty standoff placement, and when I took the cooler off (thinking it was the problem), I didn't think to clean off the slightly-melted thermal paste and put a new coat on.

So I finished the build with two major faux pas. But the thing was working great, I loaded some of my old games onto it and was having a blast with my GTX760 chewing up everything I threw at it.

But today I thought "might as well check the temps" and downloaded a few temperature reading programs.

My CPU idles at 65c and regularly gets to the 70s. Right now, it's reading in the 50s, but that's probably because I haven't done anything with it. When gaming, it skyrockets to 105c and stays there. This is obviously not good. Weirdly enough, the heatsink feels cool to the touch, which made me think that I simply had a faulty sensor, but the cpu consistently throttles itself whenever I am gaming, so I'm forced to admit that I bungled the heatsink installation big time.

Oddly enough, the thing seems fine. Even when it's running at 105c for 10+ minutes the CPU never shuts down or even throttles enough to adversely affect gameplay. But am I actually damaging my CPU? I'm gonna get a new cooler and some thermal paste eventually but I really hope this thing is salvageable. Everything else in the build works perfectly, I'd hate for the CPU to metaphorically blow up on me.

Thanks in advance.

If the heatsink feels cool, it doesn't have proper contact, and you're probably doing serious damage to your cpu by running at those temps. The only reason I can think of for it to not throttle or shut down at 105c is if the UEFI/BIOS settings for thermal protection are off, but I'd expect them to default to being on for an ASRock motherboard.

The thermal protection is on.

And if it's damaging my CPU, it's doing it crazily slowly, I left it on for several hours to download something and sometimes I game for up to half an hour on it and it's still not showing any signs of damage.

Damage usually isn't physical. Over time your cpu will just suddenly die. The cooler is probably not making contact with the cpu, thats why its cold. My computer also doesn't shut off at 105 C, but that doesn't mean its a good thing

Yeah you definitely should not leave it like that!

Pull the heatsink off, use alcohol and Q-tips (cotton swabs) to pull the current paste off, redo the paste, and redo it.

If the heatsink is cool to the touch, you're not getting any connection to the processor. I can feel the heat on the outer plastic of my Corsair H80i Water Cooler, you should be able to feel that heat.

Alright I'll buy some new paste and reseat the heatsink, but only three pins will be able to to get in. I think it's really my shitty installation that screwed up the thing, the bent pin is probably pushing the others away from the processor. I probably need a new heatsink.

Sigh...I'm a jobless high school senior. Gonna have to beg my parents to buy my a new heatsink...this build was seriously perfect in every way except this. I shouldn't run the PC at all for now, right? It runs at 65-70c even when doing nothing on the desktop.
What's a good cooler for around 30 bucks? I hear many good things about the Cooler master Hyper 212. My case is a Cooler Master HAF 912 for the matter. I hope the CPU is still salvageable.
 
The Hyper 212 EVO is an excellent cooler, but make sure your case has room for it. Better ones quickly get into diminishing returns territory, especially if you're not overclocking. If you want cheaper, you could consider the Thermaltake CLP0556:

I'd estimate the performance to be about the same as the stock cooler, but the mounting is more secure. I'm presuming it's just one of the plastic push pins of the stock cooler that broke. If the mounting holes of the motherboard are bad, then just buying a new cooler won't help any.

Yeah, it was the pin.

To clarify: when I placed the cooler on the motherboard, the bottom right pin did not line up with the hole. The other three did with their holes, but this was so far off that it just smacked into the mobo. It had to be a defect from the factory. It was like offset several millimeters from the hole and had no chance to get in. I tried to force it in, but it bent into a U-shape and now wont go in at all.

Also, one of the other three pins didn't lock into place securely, but shit, it went in and I just wanted to finish this before the day was over, I had school the next day. Looks like I paid the price.

I couldn't overclock this cpu even if I wanted to. Only thing I'm OC'ing is my Gigabyte 2GB GTX760. I don't need a cooler for OC'ing, I just want one which will keep the CPU from killing itself.
 
You're lucky you didn't break the motherboard when trying to force the last pin in, or maybe that just goes to show how cheaply made the stock cooler is. Showing your parents the bent plastic pin on the stock heatsink should be enough to convince them to buy you a new heatsink. The CLP0556 should be enough to prevent further damage to your cpu, though the Hyper 212 EVO will be quieter.

lol at the holes not lining up on the mobo... that means you installed it wrong, they always line up, its a standard size... But yeah dont worry, intel chips have brilliant thermal protection.

Btw you can overclock the 3350p by 4 bins if you motherboard lets you.

Convincing my parents shouldn't be too hard. All I have to is say "we can spend 30 bucks for a cooler or 150 for a new CPU".

I'm gonna go get a new cooler then.

Alright, so I'm planning to buy a new cooler, but how much have I damaged the CPU? Is it doomed to an early death now or is it still capable for at least another year?

I had been using it for several hours at this point (it was about 65c-75c during this). Sometimes I gamed (where it reached 105c), but never for more than half an hour at a time. I'm going to stop using it completely at this point until I get a new cooler and thermal paste.

Well, I just took off the stock heatsink since I'm not gonna be using the computer for now anyway, and now I see the problem--the heatsink clearly wasn't touching the processor. Literally about 90% of the thermal paste on it was still on the heatsink and only a smidge actually got on the IHS. Cheap-ass Intel shit...ugh. Then again I didn't exactly score high on the assembly.

I'm gonna buy a Cooler Master TX3 tomorrow (yeah I could get a Hyper 212, but it's not there so I'd have to order it online, and I'm not gonna OC or anything, plus this isn't a crazy-fast CPU anyway) or Friday at my local PC parts shop, I hope the CPU has managed to endure this literal hell it's been in.

Holy damn, guys. I bought a Cooler Master Hyper TX3 and installed it, and now my CPU is idling at 45c and barely rises above that even when playing games that would take it to 105c...glad to see that this problem has been fixed! Thanks so much!

It is loud as hell though...
