Windows 7: i5-750 temp issues

I am afraid I have to disagree with that. Got a link? Professional reviews that I am finding mention nothing about high temperature issues - in fact, they mention good temperature control, even when overclocked. I note this Guru3d review where the maximum temp they got under 100% load was only 52°C.

Any thing over 60°C is too high for me and if not overclocking indicates you have other problems, such as a poor application of thermal interface material, or insufficient case cooling.

Also note that according to the Intel warranty (AMD is the same), if that is a retail version of the CPU and it came supplied with a heatsink fan assembly, using any cooler besides the one provided VOIDS THE WARRANTY!! Not a problem if you don't care, but it is something everyone should be aware of.

Hot is a relative term. What's "hot" for one chip isn't necessarily hot for another. Yes, I don't like my chips to go over 50 too, but that's more of a personal peeve than anything else as it pertains to the i5's.

Intel states that the thermal max for the i5-750 is 95C, so "hot" for an i5-750 would be in the 80's and up. IntelĀ® Coreā„¢ i5-750 Processor (8M Cache, 2.66 GHz) with SPEC Code(s) SLBLC

About that guru3d article you linked:
This was done with a Thermalright MUX 120 air based cooler. Of course results will vary with different motherboards and cooling solutions. But as a baseline the temperatures definitely are promising, especially with overclocking in mind.
It's important not to omit the fact they're using one of the best third party air coolers ever made. Secondly, guru no longer does thermal tests in cases; instead, they've got some fancy smancy new setup thats supposed to give more accurate readings of just the cpu. I like the way they do it, however, in reality, the ambient air temp inside your case is going to always be a factor, and this value changes from case to case.

I'm not sure where you're looking, but I can't find a single i5-750 review, or forum post, using the stock cooler that doesn't show ~70C as being perfectly normal... and according to Intel, perfectly safe.

Two examples of reviews:
Intel Core i5-750 and Core i7-870 Processors - Temperature Testing - Legit Reviews
Intel Lynnfield Core i5-750 & Core i7-870 Processor Review - Page 20
In this second link, they show a side-by-side of the stock cooler vs the MUX 120.

Just a few of hundreds of pages of i5-750 guys on stock coolers asking the very same question:
intel core i5 750 temps
Temperature Issues - i5 750 - -
[Solved] Intel i5-750 [CPU Temperature] - Cooler-and-Heatsinks - Overclocking

On a personal note... for giggles, I ran the stock cooler just to see if temps really were that high before I slapped on my Thermalright; they were that high.

Lastly, and this is very important: using a third party cooler does not void the warranty. Heatsinks do not come attached to cpu's. You can use any third party cooler you wish.

I concede you are right that that CPU runs hot when stressed, but you are incorrect when you said,
Lastly, and this is very important: using a third party cooler does not void the warranty. Heatsinks do not come attached to cpu's. You can use any third party cooler you wish.
Note I did not say "attached" I said CPUs that come "supplied with". I run into this arguement so often I created a canned text with the proof right from Intel and AMD warranty pages:
It should be noted that using a 3rd party cooler on retail (not OEM) versions of Intel and AMD CPUs that come with heat sink fan assemblies voids the warranty!!! And damage attributed to overclocking is not covered under any CPU, motherboard, or cooler warranty either, regardless any overclocking features or software provided by motherboard makers. Certainly, this is not a concern for some enthusiasts. But it is a concern for many others, and everyone should be aware of it.
Intel CPU Warranty Information (my bold added)
Intel warrants the Product (defined as the boxed Intel® processor and the accompanying thermal solution)... ... if the Product is properly used and installed, for a period of three (3) years. This Limited Warranty does NOT cover:
• damage to the Product due to external causes, including accident, problems with electrical power, abnormal electrical, mechanical or environmental conditions, usage not in accordance with product instructions, misuse, neglect, alteration, repair, improper installation, or improper testing; OR
• any Product which has been modified or operated outside of Intel's publicly available specifications
AMD CPU Warranty Information (their bold)
AMD is more straightforward on their page where it says the following concerning their retail, Processor In A Box (PIB), versions of their CPUs:
This Limited Warranty shall be null and void if the AMD microprocessor which is the subject of this Limited Warranty is used with any heatsink/fan other than the one provided herewith.

This limited warranty does not cover damages due to external causes, including improper use, problems with electrical power, accident, neglect, alteration, repair, improper installation, or improper testing.
The good news is since both AMD and Intel warranty their boxed CPUs for three years, and since replacing them at their cost is not something they want to do, both make excellent cooling solutions both in terms of cooling abilities, but also in noise levels.
