What would I have to underclock an i7-9700k so that I wouldn't have to use a CPU cooler for a couple weeks?

[jynx_Moondoggie]

What would I have to underclock an i7-9700k so that I wouldn't have to use a CPU cooler for a couple weeks? I have an entire PC already, but I don't have a CPU cooler yet, and I am very impatient. I want to be able to use my PC for light schoolwork until I get it, and thats about it. I have fans that are cooling the rest of the PC, but the I don't have enough $$$ to purchase a CPU cooler yet. I was relying on the CPU coming with a cooler like non-k's and Ryzen CPU's do, but I kinda forgot that the K-Series Intel CPUs don't come with one.

So assuming you could underclock, undervolt, and disable cores to the point of being able to run it without any cooler whatsoever, by the time you did that you'd be better off browsing the internet with an abacus.

[ProjectBox153]

You simply won't be able to. Passively cooled CPUs for general desktop use haven't really been a thing since the Pentium/Pentium II days. You could look into an abacus like @flibberdipper suggested.

This makes me want to try this..... without a heat sink I mean.

 

I already web browse easily under 1000mhz with power savings mode active in W10.

 

But the cooling aspect. Could it be done? 

 

1 or 2 cores, maybe 1.2ghz at 0.8 or less v-core maybe? Include a fan directly on the IHS plate? Could it be done??!!!!

 

(I passively cool my Ryzen Athlon 220ge 4ghz ftw)

[Helpful Tech Witch]

You would need to disable all but one core, try to out it at like .5v, and run @ a locked .5ghz, and it might boot. But it would still overheat.

[NattyKathy]

This is a terrible idea. The IHS is made for transferring heat, not dissipating it.

[freeagent]

Make a heatsink out of pennies.. it would literally cost pennies to make 

[Mark Kaine]

Can't he just put like one of those adhesive VRAM thingies on the cpu?

Just order the literal cheapest compatible cooler that's got Prime shipping.

https://www.amazon.com/Intel-E97379-001-Connector-Aluminum-Heatsink/dp/B004XJNC0O

Order that.

 

Or for a couple dollars more this is a much much better heat sink that'll see you through using it at stock speeds and stock power limits.

lol I would but my CPU has a tdp of 125 watts, even the more expensive one you showed can only handle 100 watts

[Bitter]

So nothing is a better choice? $12 will do a lot more than a bare heat spreader.

If  it's only 5 bucks, I might see if I can do that as a temporary solution.

Did you already forget that you were disabling all cores but one and lock it at 500hz?

I would probably be able to run at least 4 cores and 3 ghz if I were to do this plan, however for only 10 bucks more, I found a 125w tdp cooler for 1151 Intel bracket that was only $24 on Amazon (https://www.amazon.com/PCCOOLER-120mm-Silentpro-Cooler-Intel/dp/B07MN163T6/ref=sr_1_17?crid=J5W86RRQQKV3&dchild=1&keywords=125w%2Btdp%2Bcpu%2Bcooler&qid=1615439130&sprefix=125w%2Btdp%2Bc%2Caps%2C229&sr=8-17&th=1) so that might be something I do instead

EDIT: also i just saw your pc specs and nice job on nabbing a 30 series gpu

Just wait and save some money to get something like a Cooler Master Hyper 212 or equivalent, trying to do what you are asking might cost you more money if something goes wrong, and if you are will to spend 5 bucks on the something that may not work then I believe that you may be able to wait and save 6x that amount.

That's not in stock until march 24th and then you need several days to ship it.

[jynx_Moondoggie]

Unfortunately, as I am still under 16 and don't have a job, it takes me a little bit to save up $40, especially after I owe my brother $30 after losing a bet. If only my ego were a bit smaller, my PC would have been finished a while ago.

Yea ik that's the main problem rn. By then, I would just have enough for a Hyper 212 BE RGB edition

don't have a job

Find some work or collect cans and bottles, every 5 cents counts. Some people make 50+ bucks a week just from disposing cans and bottles.

I would but I don't have enough time, I have school until 3, then I tutor my cousin until 4:30, eat dinner and then go to xc practice, get back at 7:30, shower and then play video games until 9, and then I am on my chromebook until about 11 before going to sleep

I mean ok, sure but then it would make more sense to actually wait,  I mean that's already half of your 'cooler' budget,  no?

Heh, thanks,  it wasn't even that hard  but back in December I knew I had to get one as the upcoming poor availability and rising prices was easily predictable...paid 650 euros btw

but you somehow have a 9700k

sell 9700k then

or win it back

 

do you have small aluminium plate/cup, add little water as heatsink

lol ive tested multiple mobo combinations with the lowest specs i was willing to use, i am able to use the 9700k beacause i got in a combo deal on newegg with a mobo, and that saved $75, also its taken me over 6 months to save up for the rest of the pc. All I am missing is the CPU cooler and case, but my brother has an old case that still has fans. I mean I also need a GPU, but I'm not gonna buy one rn as even a 1660s is over $700. That's why I got an APU, so that I could still use the PC until prices go down. Getting rid of the 9700k would actually make my build cost go up, and it just wouldn't be worth upgrading, I would just get a 10600k, as they have similar performance.
